It is important to investigate a pressure profile when a shock wave interacts with a reflector from a safety point of view. In this study, experiments are carried out using a shock tube of 50mm diameter and 8m in total length with a cylindrical reflector of 50mm in the observation section. The behavior of reflection process of diffracted shock wave is visualized with the aid of Schlieren techniques. As a result, (i) a pressure histories on the reflector coincides between numerical and experimental results. (ii) The sequential flow-field behind the shock wave is clearified. (iii) An empirical formula of maximum pressure is obtained with a parameter of a energy pen unit area.
