Effects of position of output electrodes in entrance region of open-cycle diagonal type MHD generator

Abstract

Effects of position of output electrodes in open-cycle diagonal type MHD generators are investigated by a two-dimensional analysis with local nonequilibrium ionization. Arranging output electrodes where the magnetic field reduces to 10–40% decreases the current concentration on output electrodes, ballast resistance required, and eddy current in end-region. The output power in end-region varies with their position to some extent and has a peak at an attenuating point of magnetic field.
