The nanosecond transversal spatial discharge with plasma electrodes is used for transonic flows with shock waves visualization in a shock tube. The discharge electric current time and luminescence time is 200 ns. Flow structure details are visualized by plasma flash glow recording. The pulse discharge visualization method allowed obtaining images of local low-density areas from two different views − upwind and downwind the streamlined model. The simultaneous instant images of discharge glow were taken by two cameras through opposite windows of the test chamber. Elements of the visualized flow structure are: shock waves, separation lines, vortices in a rear separation zone, terminating discontinuity, and boundary separation zone instabilities on glass windows surface. %8 2012-02-27
