Experimental and numerical results of oblique reflections from ramp surfaces are shown for weak shock waves in carbon dioxide. The results are shown for several combinations of the shock Mach number Ms and the ramp angle θ. Density contour fringes is photographed by using a Mach-Zehnder Interferometer. Numerical simulation is carried out by using the MacCormack-FCT combined method. There is good agreement between experimental results and numerical ones.
