Visual Investigation of Shock-Boundary Layer Interaction in an MHD Generator

Abstract

The purpose of this paper is to report gas dynamic characteristics in supersonic MHD generator, especially such as shock-boundary layer interaction occurring in the channel. The plasma for an MHD generator is produced using a shock tunnel. In order to have a clear and sharp image of the shock-boundary layer interaction in an MHD channel, the color Schlieren photographic method has been employed. The experimental results show the interaction in generator channel. The output current density decreases when the shock wave passes. The interaction in generator channel has been discussed in detail.
