Visualization of Supersonic Plasma Flow with MHD Interaction

Abstract

The purpose of this paper is to report the experimental studies of the gas dynamic characteristics, especially those such as supersonic plasma flow with MHD interaction in the constant area channel. The plasma for exeperiment is produced by a shock tube. In order to obtain a clear and sharp image of the supersonic plasma flow with MHD interaction, the color schlieren photographic method has been employed. The schlieren photographs show clealy the image of the shock-boundary layer interaction in the MHD channel. The experimental results show that the flow Mach number decreases and velocity of propagating shock wave increases in the channel, with an increase in the Lorentz force for the supersonic plasma flow with MHD interaction.
