Method and device "wave turbine ustjug"

FIELD: hydraulic power engineering.

SUBSTANCE: proposed method and device "wave turbine USTJUG" are designed for converting energy of sea waves into mechanical energy rotating the turbine. Turbine is arranged in deep still layers of water, and float holding turbinerotating shaft but not taking part in its rotation is located on water surface tasking part in wave motion. Displacements of float are transmitted through rotating shaft by means of rigid longitudinal tie with turbine, thus setting turbine into rotation. Owing to flexibility of blades, turbine moves always in one direction. Chords of blades at rest are located in plane of turbine rotation, and in active state, blades flex like wing of bird or tail of fish at stroke cross to direction of motion. Gripping of blade and power action from float to blade is provided according to rule U=0.29 in direction cross to plane of blade motion. Blades are arranged in pairs symmetrically relative to rotating shaft on crossmember to form separate element of turbine with torques of same signs for both blades number. Of such elements arranged along turbine rotating shaft determines power of turbine rising in proportion of number of turbine elements whose relative arrangement in angle of plane of rotation and element-to-element distance of rotating shaft is determined to provide maximum efficiency of elements in operation.

EFFECT: effective conversion of wave energy and reliability in operation.

The invention relates to the conversion of the reciprocating motion of the fluid caused, for example, by the sea, in the one-way rotational movement of the turbine.

The level of technology

A device windmill or a wind turbine (Back. Introduction to technical hydromechanics. M. - L.: 1941, Gosenergoizdat, - 256 C.). It on the shaft of rotation in the plane perpendicular to the shaft axis of rotation fixed several blades, which under the action of wind are set in motion, asking if this rotational movement of the shaft rotation.

The disadvantages of the known devices include:

- low coefficient of performance (COP): the maximum theoretical efficiency is less than 60%, the real is in the range of 15-25%;

the unidirectionality of the wind turbine relative to the wind direction specifies the direction of rotation of the shaft.

It is known (Ageev, VA non-traditional and renewable energy sources (lectures), http://dhes.ime.mrsu.ru/studies/nrps/lectures/lecture12.pdf device that uses the principle of an oscillating water column (developing National engineering laboratory NEL, UK, is placed directly on the ground, the turbine is driven flow in one direction), while the valve system of direct and reverse air flow, changing the direction of movement under the action of the oscillations of the water column, come to the turbine with one hand.

The disadvantages of the known devices include:

the loss of efficiency of the device due to the energy loss accompanying the process of passing a fluid flow valve system and knees, changing the flow direction;

- remains inefficient principle of operation of the wind turbine;

Known turbine wells (Twidell J., The Weir A. Renewable energy sources: Lane. from English. - M.: Energoatomizdat. 1990. - 392 C.), which has constant sign rotational moment occurs regardless of the forward or reverse direction of the fluid flow. This is achieved by the shape of turbine blades having an aerodynamic profile in the form of drops, elongated in the direction of movement of the blade in the plane of rotation of the turbine. In the fall flow blade at an angle to its surface, which differs from a right angle, a component of the forces acting on the blade, pushing it out of the stream in the direction perpendicular to the axis of rotation of the turbine. In the turbine acquires rotational movement, supported by the combined effects of all of the blades, available at the turbine. Because of the symmetry of the profile of the blade relative to the plane of rotation of the turbine exposure to direct flow similar to the effect of reverse flow, resulting in a turbine in both cases is the bottom and the same direction of rotation.

The disadvantages of turbine wells include:

- low coefficient of performance (COP). Due to the fact that the wells turbine is a wind turbine, although bilateral, its (cap) in the ideal case can be estimated as less than 60%, and in real from 15 to 25%;

- selectivity in the interaction efficiency of the blades and flow due to the fixity of the profile of the blade, which in the turbulent wave spectrum leads, consequently, to a significant loss of overall efficiency of the turbine;

because of the fixity of the profile of the blade is excluded resource potential of increasing the efficiency of the turbine by reducing resistance;

- fixity of the airfoil blade and mechanistic approach to the emergence of the driving force of the blade due to the reflection of the flow from an inclined plane represent a surrogate of the two sections of the physics of rigid body dynamics and aerodynamics, streamlined profile, which leads to inefficient variant of the turbine;

the principle of operation of the turbine sets such geometry flows through it, which leads to additional costs for the construction of structures that define workflows and reduce the effectiveness of the entire structure;

the geometry of worker threads and turbine eliminates the capacity on the turbine shaft by ka is odnogo location on groups of consecutive turbines;

- turbulence outer atmosphere in a stormy period significantly affects the efficiency of the turbine wells.

Known (http://www.energetech.com.au/) development of Australian inventors turbine Dennisse Sr. (The Demiiss-Auld Turbine). In this turbine, the angle of attack hard blades is controlled via touch sensors that allows to take into account the dynamic change of direction of the air stream to the reverse and save repeated rotation of the turbine.

The disadvantages of the known tools are:

the same inefficient the principle of operation of the wind turbine, i.e. essentially grabowy way to create thrust blades;

- hard blades reduce the efficiency of the device;

- introduction to device control blades, complicating the device, which inevitably leads to decrease in the reliability of the turbine.

Closest to the proposed technical solution is our "Method and device for moving body flooded" (patent No. 2259302 EN), which is planar or volumetric hydrodynamically being wrapped flexible elastic body, which is in fluid transverse to the surface of the profile direction in a certain area that meets the rule U=0.29, a force is applied. This causes the body of the thrust force in the forward direction, transverse to the direction of the Department of applied force.

A known solution can be expanded in view of its applicability for the case when the force acting on this body, created by the energy, for example, of the waves.

The purpose of the proposed solutions - development of the method and device of the turbine, the rotational movement which occurs under the influence of fluid when the reciprocating motion of the turbine relative to the environment or the environment relative to the turbine along the axis of its rotation, devoid of the above disadvantages of the known technical solutions and a natural development of our well-known technical solutions.

The objective is achieved by using as the turbine blades flat or three-dimensional hydrodynamically streamlined flexible elastic body, the area on the hard grip which satisfies the rule U=0.29, and the rest of the chord of the blade is located in the plane of rotation of the turbine perpendicular to the axis of rotation of the turbine, and the turbine itself consists of n separate elements attached to the shaft of rotation of the turbine, each of which is composed of two or more blades, symmetrically located relative to the shaft of rotation of the turbine, while the thrust force of the blade occurs under the influence of fluid when the reciprocating motion of the turbine relative to the environment or the environment relative to the turbine along the axis of its the treatment due to flexible deformation of the blade, such deformations of the wing of a bird or fish tail during flight movement, and occurrence of vortex motion in the transverse relative to the direction of centrifugal movement direction.

THE ESSENCE OF THE INVENTION.

A. When developing "Method and device for moving body flooded" (patent No. 2259302 EN) we have obtained that, when exposed in the transverse direction on a flat or three-dimensional hydrodynamically streamlined flexible elastic body type wing, located in a fluid environment in a certain area thereof causes a thrust force, forcing the body to move forward transverse to the force acting direction.

Let us explain this.

First of all, special attention should define the scope of application of external force to the mover.

Consider (1) the body under the action of external forces. For definiteness, let it be a flat plate of rectangular shape with dimensions of l×k, where l is a transverse, a k - its longitudinal dimensions, and l<k. Consider the plate will be in the XOY-plane rectangular coordinate system formed by the axes X, Y and z In the longitudinal direction of the plate is directed parallel to the Z axis coming out of the sheet. As a result, the XOY-plane projection of the plate will look like a line segment AB is a straight line of length l. The origin, point O, we choose so that the at will coincide with the point of thrust, with an initial length ρabout. The OX axis will refer vertically down so that the straight line connecting the point On the plate, will coincide with the axis OX. The axis OY forward towards emerging translational motion of the plate so that the trajectory as flat curve will be located in the plane XOY. The point To denote the geometric center of the line segment AB, which is in our case the center of mass of this segment. Point O' denote the capture point thrust (cable) plate on the line segment AB.

There are two extreme situations: one is when the thrust plate captures the point corresponding to the maximum fuselage mid-section, i.e. at the point where the shift FROM'=δ the capture plate thrust equal to δ=0. In this case, applied to the plate of the external force will cause the maximum oppositely directed force of the reaction environment. This leads to maximum losses in connection with performance of work required to overcome the force of reaction medium, and the thrust force does not occur. Performance in this case is low. The second situation is when the thrust plate captures a point in the middle of the front line of the plate. On the plane XOY this position corresponds to the point And the line segment AB, where δ=l/2. In this case, the tensile force of traction, external power, minimum. When the plate ishorizontal position is first of all, the rotation plate to the position close to the vertical. The thrust force does not occur. Which is the efficient application of force in this case is low. You should expect between the two extreme cases, when δ=0 and δ=l/2, there must be a point, the capture plate which will promote maximum efficiency due to the thrust force as the result of two inevitably existing primary forces external forces and reaction forces of the environment.

The efficiency of external power will be estimated by the maximum of the resulting thrust force depending on the parameter δ. Physically, it should look like that under the application of external force to the propulsion force occurs in the reaction medium. The vectors of these forces add up and give the resultant vector forces, resulting in forward movement of the plate along a curved path.

Estimate the distance δon which should be the point of the outer thrust plate with respect to the geometric center of this plate.

In figure 2, as shown:

XOY - original rectangular coordinate system, point O - point thrust, for example, a rope;

X"On"Y" - coordinate system associated with the instantaneous axis of rotation passing through the origin O". Let the body's position in space will be characterized by any visiting th is this body, for example, as in our case, the point of his capture. Then the coordinate system X"On"Y" is because when curvilinear motion of a body has an axis, which at a given moment of movement is at rest, i.e. the body at this point, how would rotates around this axis passing through point O". This axis may, as in our case, to be outside of the body. And the resulting curvilinear path of motion of the body will be a set of points, sequentially formed by a set of positions in space of the point of capture.

ρ - instantaneous length of the rope;

ρ′ - the distance from the point of capture plate to the instantaneous axis of rotation On";

F - vector of the applied traction force of the cable (hereinafter, bold letters will denote vector quantities);

N is the vector of reaction forces of the environment.

In figure 2, b shows:

AB=l - the width of the plate;

l1- shoulder forces f1;

f1the force vector that specifies the rotation of the plate around the point O', associated with the capture plate rope;

With the center of mass of the plate and at the same time its geometric center;

O=δ - offset distance of the point of capture plate from the center of mass;

Fn=F·CosαN' is the normal component of the resultant force acting on the plate from the rope;

Fτ - the tangential component of the force acting on the plate from the rope;

F'=Fn+Fτis the resultant force that makes the body move progressively along a curved trajectory that is different from the circumference;

β - the angle between the instantaneous direction of movement of the plate and the Y-axis;

γ - the instantaneous value of the rotation angle of the instantaneous radius ρ' with respect to the axis O"X";

ϕ angle of rope to vertical axis X;

α - the angle between the rope and the instantaneous radius vector ρ'.

The moment M1(low-fat letters hereafter referred to modules corresponding vectors) forces Fτapplied to the plate and having a shoulder ρ', is determined by the product of the force on the shoulder. The same torque is determined by the moment of inertia JOsystem and acquired angular acceleration d2γ/dt2. Then the equality

(Nigericin, Cinebistro, Pscreen. A brief Handbook of physics. "High school". M, 1962).

Another moment M2forces f1acting on the plate with the shoulder l1and in this case the moment of inertia is JO'and angular acceleration - d2β/dt2is determined by the equality

Consider the case of an equality of angles γ=β and soo the relevant angular acceleration d 2γ/dt2=d2β/dt2.

Case γ<β corresponds to the fact that d2γ/dt2<d2β/dt2i.e. in accordance with the geometry figa, b plate under the action of the cable will turn clockwise. This plate will be available progressive movement back. Case γ>β corresponds to the fact that d2γ/dt2>d2β/dt2i.e. the plate under the action of the cable will turn counterclockwise. But according to the geometry figa, b will decrease the strength of the reaction medium N. the force F is simply a force pulling the body, but not the force that acts transverse to the translational direction of movement flooded the body.

Then the equality

Because

(m - effective and evenly distributed weight plates, including attached weight [Landau L.D., Lifshitz E.M.. Hydrodynamics. "Science". 1988]),

then from the equality (3) subject to (4), (5) and (6) follows

Denoting the totality of factors that do not depend on δ, letter To, equal to

let's rewrite the equality (7) in the IDA

Then the first derivative of Fτ' Fτδ can be written in the form

Equality to zero of the first derivative Fτ'=0 determines the value of δwhere the function Fτ' has an extremum (Ingebrigsten, K.semendyaev. Handbook of mathematics. "Science". 1964). Omitting the obvious intermediate expression and convert, record,

And since the second derivative of Fτ" less than zero

the resulting value δ determines the maximum of the function Fτfrom δ.

If we consider that the thrust force Fτ=F·Sinαit appears that when

submerged body gets the maximum tangential acceleration at a given applied force F and increases with increasing angle α proportional to Sinα.

This same angle α sets the angle between the force vector N of the reaction medium acting on the plate, and a straight line, along which has applied to the plate of the force F.

It follows that the elasticity and flexibility of the plate should in the process to set a value of an angle α for chord, which corresponds to the condition of occurrence of the maximum force the Yaga.

Thus, it appears that the placement of the capture plate in accordance with condition δ=0,2887·l or rule U=δ/l=0.29 allows you to achieve optimal conditions for the movement of the plate under the action of the resultant of two forces - the traction force of the cable and the reaction forces of the environment. In this case, the translational motion of the body energetically optimal if only because the movement of the plates is carried out in accordance with those conditions that lead to the minimum energy losses of the moving body. Ie, having at its disposal the equipment, allowing to develop traction force F, it is necessary to determine the point of capture plate on the basis of the obtained conditions. Then the resulting velocity of the plate is maximum, and the corresponding expenditure of energy to overcome the forces of resistance to the environment is minimal.

You must pay attention to the fact that the point characterized by the condition δ=0,2887·l, is close to the so-called focus of a wing profile determined from other considerations. This concept is used in aircraft construction (Ammiture. Aerodynamics. M: Engineering. 1976. 448 C.) when choosing the optimal shape of the wing in order, in particular, the definition of the profile of the wing in which the wing will have a maximum lifting force at its best quality. the ri this wing of the plane hard, and not flexible, which affects the efficiency of the wing, depriving it of its versatility.

During the experiments we found that a flexible elastic body, captured in accordance with rule U=0.29 and under the influence of an external shear force, has better dynamic performance maximum thrust and minimum loss of energy at a given value of the acting force.

B. In our research (Ustulina G.P. "Flying in the air and water environments". The Newspaper "Physics", No. 29, Ed. Home "First of September". 2004) it is shown that for the primaries birds from sparrows, Tits, urban crow and a dove to gulls Falcon and stork characteristic is the equality of the parameter U=0.29. It was determined by measurement of mutual arrangement of the webs and the barrel of the pen. The stem is that part of the pen, through which the shock primary is the interaction of the wing from the air environment. I.e. natural propulsion confirm validity of rules U=0.29 as the best to create the maximum thrust from a flexible elastic aerodynamically streamlined flat or close to the volume of the body under the influence of the lateral force with minimal loss of energy.

C. Further our research was to apply the result of paragraph (a (rule U=0.29) in the case of unilateral and alternating impact on those is about to create thrust forcing the body to move along a curved trajectory with a monotonic change of direction, and the average translational in one straight direction.

Let (3) the plate will be fixed by the thrust in the form of cable and movable along the axis OH of the stem, through which the impact on the plate. Let the rod will be prevented from rotation at a point On the coordinate system XOY. And the point About let it be rigidly connected, for example, with the craft. Then (3)if implementing external influence in the form of alternating periodic force, forcing the point of the capture plate to reciprocating motion, then we should expect the appearance of the resulting thrust forward. This thrust force applied to the swimming apparatus, will lead to its forward movement. This made the forced vibrations of the capture plate will be movements, transverse relative to the direction of movement of the craft, which ideally corresponds to the flapping motion of the wing of the bird and the tail of a fish. At the same time this means that all the excitation thrust forces in fluids oriented oscillatory weerapana propulsion fundamentally contradict the condition for maximum efficiency δ=0,2887·l and, therefore, by definition, have a lower efficiency than in the proposed case.

In this case, does not arise a necessity in order to set the angle of attack of the propeller, since the thruster under the influence of external forces and conditions itself, warping, takes energetically favorable shape and angle of attack.

When the propulsion occurs vortex flow (figure 4), which are formed sequentially descending from thruster closed vortex type the Torah. When the direction of vortex flow (figure 5) is opposite to the direction of thrust. The thread is formed by a group of vortices forming behind the propulsion track type track Pocket (N.e.kochin, Navroze. Introduction to theoretical fluid mechanics. GOS. technical and theoretical publishers. M.-L. 1932 316 pages). Here the analogy with painting the occurrence of the lifting force of the wing moving in a fluid environment with some speed: at low angles of attack, which is about 5-10 degrees, the wing there is a significant lifting force. In our case, by applying the external force plate so that it plays the role of a lifting force, and deformation of plate bending cause its shape to the shape of the wing, we create for external fluid conditions under which the resultant swirling motion of the environment should be such that it corresponded to the lifting force. In this sense, our method of excitation of the motion of the medium is the opposite way of the occurrence of the lifting force of the wing is located in a moving stream. In this case excluded the application of the fluid as the time and therefore excluded the element of motion "failure" mover on Wednesday, when he, as Grabovoi tool, used to rely on the fluid.

The problem of inefficient stage shifting mover" in the proposed solution is removed completely so that the mover is in this stage that straightens and returns the potential energy of bending in the form of kinetic energy of the translational motion of the swimming apparatus forward.

In our experiments propulsion using the method of physical modeling of the obtained efficiency≈76%. Under similar conditions the screw-propeller efficiency has≈45%.

, The Application of our propulsion in a variant, the blades of the turbine gives the device initially has high efficiency and constant sign of the moment of rotation with alternating direction of flow of fluid to the turbine.

Figure 6 shows the turbine element, consisting of two blades 1 mounted on the cross member 2 in the area corresponding to the rule U=0.29 for the blades. The cross member 2 is rigidly connected with the shaft 3, having an axis of rotation 4. This is the element of the turbine at rest. The movement of the element along the axis of rotation, i.e. in the positive direction of the Z axis leads to Flexural deformations 5 blades, the opposite movement leads to Flexural deformations 6 blades. In both cases, the element of the program is retait rotational movement in the direction 7 - counter-clockwise. An increase in the number of turbine elements, sequentially disposed on the same shaft rotation, leads to a proportional increase in the power shaft rotation. This allows you to build up the necessary capacity on the same shaft as the rotation of the turbine without increasing the transverse dimensions of the turbine wheel.

The movement of the element along an axis in the stop, i.e. in the positive direction of the Z-axis, which leads to a bending deformation of the blades 5, the opposite movement leads to Flexural deformation of the blades 6.

The blades are made of flexible elastic polymer film thickness of 0.00025 m so that they form a rectangular body with dimensions of 0.07×0.105 m2. In the area corresponding to the rule U=0.29, created a pocket 10 for draping and securing the blade 1 on the cross member 2.

Rotation of the shaft 3 drives the gear 9, which, in turn, through the transmission gear causes the rotation of the small gear mounted on the generator shaft 12. The gear ratio of the gears 132:8. The rotation of the turbine on the findings of the generator 13 there is a potential difference. As the electric generator is used mi is adigital DC in reverse mode. The DC motor PDM-25-N1-03 is designed for a supply voltage of 12 V and a current of 0.3 A; angular speed - 6000 rpm as the indicator led brand GNL-1206URC red with a working voltage of 1.9 V and rated current of 70 mA, connected to the terminals of the generator. To simulate the movement of the float on a wave you can use the manual option: holding device for the float produced by the vertical oscillatory motion of the device so that the three-element turbine is submerged condition. When this occurs the rotational movement of the turbine which is not dependent on the forward or reverse direction of movement of the device, stimulating in the circuit of the generator-led electric current. On 11 photos in color and Fig in black and white you can see the device under the action of vertical movements of the hand device, captured for the float, with the turbine submerged in water, lights the red led 14. The led connected to the outputs of the generator 13 and for ease of photography mechanically attached to the tripod 15. Torque measurement and measurement of voltage and electric current given the following results (table 1). The maximum value of the applied force chose equal to 3.0 N. The average applied force 3.0×0.5 acted within 0.5 s on the vertical interval is the material displacement device, equal to 0.06 m, which determined the average speed as 0.12 m/s and angular 1.0 Rev/s Power applied to the device, equal to 3.0×0.5×0.12=0.18 watts. The measuring voltage (2.0 V) and current (0.5 a) on led connected to the terminals of the generator, provided an assessment of the output (useful) power 2.0×0.5=0.1 watts.

Table 1.
Power, N.Speed, M/sPower, WVoltageCurrent AndPower, W
3.0×0.50.120.182.00.050,10

As a result, the efficiency of the device was equal to 0.1/0.18=0.56=56%.

If we consider that the efficiency of the generator (back of engine) can be measured in the range from 60 to 80%, then the turbine efficiency can be obtained valuation from 93 to 70%.

Thus, the proposed technical solution is economically more favorable than known solutions. The reason you win is that we are moving away from the use case fluid as a prop for propulsion, as in this case, the mover will always "fall" in the environment, its effectiveness will be how much fluid mass per unit time he's USP is et to alienate. But this is closer to jet propulsion, and in the most economically viable option. Our idea is that the driver creates the conditions for the occurrence of vortex flows, i.e. flows that occur during flight the wing movements of poultry or tail of a fish, the efficiency of which approximately 95%.

The proposed solution is naturally allows the following extensions:

- turbine can be located not only in water, but in air environment;

- on the same shaft rotation possible joint use and underwater and air turbine options.

SUBSTANCE: proposed method and device "wave turbine USTJUG" are designed for converting energy of sea waves into mechanical energy rotating the turbine. Turbine is arranged in deep still layers of water, and float holding turbinerotating shaft but not taking part in its rotation is located on water surface tasking part in wave motion. Displacements of float are transmitted through rotating shaft by means of rigid longitudinal tie with turbine, thus setting turbine into rotation. Owing to flexibility of blades, turbine moves always in one direction. Chords of blades at rest are located in plane of turbine rotation, and in active state, blades flex like wing of bird or tail of fish at stroke cross to direction of motion. Gripping of blade and power action from float to blade is provided according to rule U=0.29 in direction cross to plane of blade motion. Blades are arranged in pairs symmetrically relative to rotating shaft on crossmember to form separate element of turbine with torques of same signs for both blades number. Of such elements arranged along turbine rotating shaft determines power of turbine rising in proportion of number of turbine elements whose relative arrangement in angle of plane of rotation and element-to-element distance of rotating shaft is determined to provide maximum efficiency of elements in operation.
