 Method for determination of stable and unstable operation zones of cylindrical linear electromagnetic induction pumps / 2324280
Method consists in determination of stable and unstable operation zones of cylindrical linear induction pumps with three-phase excitation winding having a flat-wave linear current characteristic. Coils of the excitation winding have a constant number of turns throughout the length of the inductor and create a traveling variable magnetic field within a cylindrical liquid metal channel operating at a magnetic Reynolds number Rm>l and having an approximate boundary between stable and unstable operation zones. These zones are determined by the point of intersection of two modified parameters: magnetohydrodynamic interaction αRN and magnetic Reynolds number αRm. The point of intersection of said parameters is applied to the plane of a curve being deduced from experiments αRN=f(αRm). Moreover, if said point is situated below the curve then the pump operates stably, and if it is above the curve then the pump operates unstably, wherein

FIELD: propulsion devices. SUBSTANCE: electromagnetic propulsion device incorporates a housing with a water intake and discharge channel accommodating the main electrodes to generate current in electric field enveloping the said channel section and a device to generate a magnetic field oriented perpendicular to the said electric field to create the main Lorenz force. The propulsion device working channel incorporates, at least one pair of additional electrodes isolated from the main ones to ensure an electric breakdown of water and to create an additional Lorenz force aligned with the main one. EFFECT: higher efficiency of the proposed device thanks to artificial increase in water electric conductivity. 2 dwg
The present invention relates to engines operating on the electromagnetic effect of creating a reactive force which provides for the movement of the vessel. Known for the propulsion of ships and submarines, the design of which implements the influence of electric and magnetic fields in the environment movement and contains the electrodes and the electric magnets (RF patent No. 2271302, VN 19/00; RF patent №2280587, VN 11/04, 11/02), while on the surface of the moving body are mutually perpendicular electric and magnetic fields. The electric field provided by the electrodes, electrically connected with water and placed on a circle on the surface of the body in the plane perpendicular to the direction of motion and the magnetic field of magnets located inside or outside of the body. The design of these engines allow the use of sea water in which the vessel moves, as a working medium, which is moved relative to the vessel under the action of the Lorentz force in the direction opposite to the movement of the vessel (Handbook on the physics Chukling, "World", 1982, s-349). The closest technical solution to the proposed propulsion is electromagnetic propulsion in sea water (U.S. patent No. 6333444, VN 11/00), comprising a housing with a working channel for inlet and outlet of water, which are devices for Generalov is of current mainly due to the proton conductivity in the electric field, covering the working channel, and a device generating a magnetic field perpendicular to the electric field. Based on the simultaneous action of electric and magnetic fields occurs Lorentz force, which provides the buoyancy of sea water in the direction opposite to the thrust force of the vessel. However, due to the low conductivity of the sea water mover efficiency is low. The technical result is to increase the efficiency of the proposed propulsion due to artificially improve the conductivity of the water. This result is achieved by the fact that in the electromagnetic propulsion device, comprising a housing with a channel for the inlet and outlet of water, in which the main electrodes to generate a current in an electric field, covering a section of the specified channel, and device for generating a magnetic field, oriented perpendicular to the electric field, to create a basic Lorentz force mainly due to proton conductivity, according to the invention in the working channel have at least one pair of additional electrodes that are isolated from the main electrodes to provide electrical breakdown of water and the generation of high current density mainly due to electronic conductivity. the additional electrodes are placed in the channel with the possibility of creating additional Lorentz force, coinciding in direction with the field above the main Lorentz force. The proposed device allows to increase the conductivity of the water, resulting in increased total Lorentz force acting on the working volume of the water and eventually increases the efficiency of propulsion. Figure 1 shows the proposed propulsion, figure 2 - cross section, specify the polarity of the primary and secondary electrodes, and the direction of electric and magnetic fields. The device includes a housing 1 with a working channel for passage of water (the direction indicated by the arrow in figure 1). In the working channel are the main electrodes 2, which are, for example, flat plate, the long side of which is directed along the working channel. Also in the channel are devices generating a magnetic field 3, isolated from contact with water. They represent, for example, magnetic dipole, consisting of two conducting electric current to the coils located on either side of the working channel. For General homogeneous magnetic field, covering the working channel, the magnetic field of the coils must be the same in direction. Additional electrodes 4 in the form of a thin pointed pins are isolated from the main electrodes and located so that when electrical breakdown of water generated by the additional Lorentz force coincides in direction with the main force. The propeller provides thrust of the vessel in sea water as follows. Device generating a magnetic field 3 create in the working channel of a uniform magnetic field. Upon application of an electrical voltage to the main electrode 2 under the action of electric field intensity occurs the movement of Na ions and protons H toward the negatively charged electrode and the movement of ions mainly Cl in the opposite direction. The Lorentz force acting on the charges, proportional to the speed of their movement in the water, i.e. their mobility. The mobility of the ions Na and Cl, the main hydrated ions in sea water, salts, ≈ 100 times lower than the mobility of the protons H. Given the small concentration of salts in seawater, the main the Lorentz force will depend on the movement of protons, and the conductivity will be mainly proton character. When electrical breakdown of water between the two additional electrodes 4 arises gas "tube", which along with the above charged particle creates the possibility of movement of free electrons, which will move towards the more positive electrode. The mobility of the electrodes in the gas pipe " " 100 times higher than the mobility of the protons, and four orders of magnitude higher than the mobility of the ions listed above. Therefore, the conductivity of the gas in Proc. of the BKE between the additional electrodes will be mainly electronic in nature. The associated additional Lorentz force will mainly depend on the movement of electrons. The polarity of the main and additional electrodes (figure 2) provide the General direction of the Lorentz force and the movement of sea water in the working channel in the direction of arrows in figure 1. Under the simultaneous action of a magnetic field, the primary and secondary electric fields increases the electrical conductivity of the water in the working channel, the Lorentz force are summed, the result is achieved technical result - mover efficiency increases. Electromagnetic propulsion, comprising a housing with a channel for the inlet and outlet of water, in which the main electrodes to generate a current in an electric field, covering a section of the specified channel, and device for generating a magnetic field, oriented perpendicular to the electric field, to create a basic Lorentz force, characterized in that the working channel is installed at least one pair of additional electrodes that are isolated from the main electrodes, with the possibility of electrical breakdown of water and create additional Lorentz force, coinciding in direction with the principal.
