Abstract
The experiment on oblique shock reflection has been carried out by means of a shock tube and a model wedge. The incident shock Mach number M was about 1.42 and the working gas was air. Waves were visualized and analyzed by schlieren photography. Attention was focused on the quantitative analysis of the unsteady behavior of the triple point. The evolution of waves were discussed from the viewpoint of its effect on the behavior of the triple point. The rarefaction wave generated at each corner of bumps pulled the triple point down, and consequently the value of the angle of reflection ?? increased abruptly.
