The purpose of present paper is to report the experimental studies of the gas dynamic characteristics, especially those such as shock wave-boundary layer interaction, in a supersonic MHD generator with constant area channel. The plasma for MHD generator is produced by a shock tube. In order to obtain a clear and sharp image of shock wave-boundary layer interaction in MHD generator channel, the color schlieren method has been employed. The experimental results show that a pressure rise occurs through the shock wave. The schlieren photographs show the bifurcation of shock wave and the separation bubble due to the shock wave-boundary layer interaction in MHD channel. As a result of this interaction, the passing of the shock wave reduces the output current over an axial distance of several duct diameters downstream.
