The structure and behavior of a vortex ring and secondary shock waves which were generated behind the shock wave discharged from the open end of a square cross section shock tube were investigated experimentally and numerically. Double exposure diffuse holographic interferometry was used to observe this complicated three dimensional shock wave phenomenon. This diffuse holographic interferometric visualization is particularly useful to understand three dimensional flow. The TVD finite difference numerical simulation was carried out by solving the three dimensional unsteady Euler equations. A comparison was made between experimental results and computational results. These results clarified the generation and the transformation of the vortex ring and the behavior of three dimensional secondary shock waves.
