Abstract

The head-on collision and subsequent reflection of a regular reflection (RR) from the end-wall of a shock tube has been investigated experimentally and numerically. 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.
