Experimental investigation of bracket electrodes protruding into the flow in the channel of self-excited pulsed MHD generator of the Pamir type

The results are given of experimental investigation of a Faraday-type pulse d MHD generator with discrete bracket-shaped wire electrodes protruding int o the flow. The process of self-excitation is more intensive than in the ca se of conventional flat continuous electrodes. For the maximum parameters o f MHD interaction, the parameters in channels with discrete bracket electro des and flat continuous electrodes, in the vicinity of which the state of t he boundary layers is respectively different, are perturbed sharply under c onditions of virtually the same parameters of MHD interaction, this being i ndicative of the decisive effect of volume electrodynamic forces on these p rocesses.
