Description

one

The invention relates to the conversion of mechanical energy of a moving electrically conducting fluid into electric current using MHD devices and can be used to create strong magnetic fields without the use of superconductors.

A known method for producing a magnetic field using solenoids. If it is necessary to create strong fields, it is necessary to increase the number of ampere turns, or, at a certain density of turns per unit length, the current of the solenoid. The increase in current leads to the need to cool the winding and increase the mechanical strength of the solenoid.

The proposed method allows to obtain strong magnetic fields under high temperature conditions.

This is achieved by the fact that the annular operating current, which creates a magnetic field, is generated by the organized movement of an electrically conductive fluid in a magnetic field of excitation and flows through this electrically conductive fluid, which in this case is simultaneously a heat carrier, and the mechanical load that occurs during flow strong currents, perceived by the autoclave. In this case, the flow of electrically conductive liquid is passed through flat parts with electrical contact and channels forming a closed ring in mutually perpendicular directions, so close to each other so that

The vector of the flow velocity during the transition from the channel to the channel in the direction of the magnetic field of excitation, the lines of force of which lie in the plane of the cross section of the ring, turned pa by 90 ° in one direction. In this case, the EMF, which creates the working ring current, is indicated in each channel by the magnetic flux due to the electric current in the adjacent adjacent channels, and is directed along or against the direction of the magnetic excitation field.

On fng. 1 shows electrically conductive partitions separating the channels; Yao's magnetic field is perpendicular to the partitions; in fig. Figure 2 shows the directions of the flow rates v, V2, ..., V6 in the channels and the magnetic excitation field of Yao; in fig. 3 - for the channel channels 1, 2, ..., 6, the directions of the magnetic field of the Yao field, the flow rates v, the current r induced in

the result of the interaction of the fluid flow with the magnetic field But, the magnetic field Hn formed in each channel by the currents of adjacent channels closed with each other, and

The emf E arising from the interaction of the flux with the HI field (this emf is working and creates a current causing a magnetic field) - in FIG. Figure 4 shows schematically a half of a ring formed from partitions, which are the walls of the channels. In this case, the magnetic field of excitation Ho lies in the plane of the cross section of the ring, and the emf generated. E causes a ring operating current.
