Abstract
This paper examines the dependence of the attenuation of magnetic induction on the current distribution etc. in the exit regions of the Faraday type non-equilibrium plasma MHD generator by a two-dimensional calculation. The numerical analyses are made for an example of the cesium-seeded helium. As a result, a reasonable magnetic induction attenuation can make the distribution of current very uniform near the exit region of generator channel and has little influence on the current distribution in the middle part of generator, and the output electrodes can be used without great ballast resistors. Also the inside resistance of the exit region and the current concentration at the exit electrode edges decrease with the attenuation of magnetic flux density. By the author's examination, it is made clear that the exit electrodes of the diagonal Faraday type non-equilibrium plasma MHD generator should be arranged in the attenuation region of the magnetic induction, since arranging them in this region becomes useful for the improvement of the electrical parameters of generator.
