概要 |
The purpose of the present paper is to report the results of visual studies of the supersonic plasma flow in the Faraday type MHD generator with constant area channel. The plasma for MHD generator is ...produced using a shock tube. In order to obtain a clear and sharp image of the supersonic plasma flow in MHD generator channel, the color schlieren method has been employed. The experimental results show clearly shock waves and Prantle-Meyer fans in MHD channel. In the case of the flush mounted electrode channel, the adjusting wave is formed at the end of channel and moves to upstream. The pressure increases smoothly and the flow Mach number decreases from supersonic to subsonic through the adjusting wave. The plasma flow in a channel with protruded electrodes is also investigated, and the characteristics of the multiple shock wave which appear between electrodes are discussed.続きを見る
