Electrical Effects Accompanying Flow of Gas in Shock Tube

摘要

During the passage of strong shock waves, a flow of thermal ionized gas will be formed behind the front. Processes of diffusion, developing in the front, can lead to large gradients of electric potential along the direction of propagation of the front which are very difficult to measure. Analogous processes of diffusion and thermal diffusion behind the shock front can, in the presence of walls, lead to the appearance of potential differences between the flow of ionized gas and the wall.
