Abstract

The gasdynamic process of shock wave reflection at a curved obstacle performed by shock. tube runs is visualized interferometrically with the aid of a Mach-Zehnder interferometer. A. fast rotating prism framing camera in connection with a special point light source of adjustable duration produces about eighty colored interferograms with finite fringe width, the time-distance being constant (1 or 2 microseconds). Evaluation. of interferograms yields shock front pressures which are compared with pressure values gained by piezo-electric measurements.
