摘要

采用局部非平衡电离的二维分析方法，研究了开循环对角型MHD发电机输出电极位置的影响。将输出电极布置在磁场减小到10-40%的位置，可以降低输出电极上的电流浓度、所需镇流器电阻和端区涡流。端区输出功率随其位置有一定的变化，在磁场衰减点处有一个峰值。

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

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.
