Paper Abstract

A holographic interferometric study was made of the structure of a shock wave discharged from a square cross section shock tube. To visualize the present complex three-dimensional shock wave phenomena, two- and three-dimensional holographic interferometry was applied. The results indicated that the vortex which was generated from the shock tube exit changed its configuration from a square shape to a cylindrical shape and that the secondary shock wave has a complex three-dimensional shape. To compare the experimental results, a numerical simulation using the TVD finite difference scheme was conducted and good agreement was obtained. It is pointed out that quantitative holographic interferometry is particularly useful to validate the CFD code.
