Abstract
Presents a theoretical investigation on elimination of current distortion caused by the Hall effect in Faraday-type MHD power generators. Taking as an example an MHD generator with a pair of electrodes opposed, and applying the conformal transformation technique to the generator channel, it was shown that the excessive current concentration at the electrode edges due to Hall effect can be completely eliminated by adopting suitably variable resistive electrodes, and therefore, the current distribution in the generator channel is not influenced by the Hall effect. This method is based on the principle that the induced Hall field is exactly compensated by the potential gradient produced by the current flow in the resistive electrodes.
