The head‐on collision and subsequent reflection of a Regular Reflection (RR) from the end‐wall of a shock tube has been investigated both experimentally and numerically for two different incident shock wave Mach numbers and two different reflecting wedge angles. The agreement between the double‐exposure holographic interferograms and the numerical simulations which were obtained using a GRP based numerical code, was found to be excellent in the RR region and very good behind the head‐on reflected RR. The overall good agreement between the computed and experimental constant‐density contours (isopycnics) constitutes a validation of the computational method, including the oblique‐wall boundary condition.
