Abstract

The aim in this paper is clarification of the role of shock waves in compressible turbulent flows by comparing shock wave interaction with baffle plates of a solid and a rigid porous materials. As the basic research for this purpose, experimental investigation of the shock wave attenuation over solid and rigid porous baffle plates is presented. These models with two different heights are installed in 60 mm x 150 mm diaphragmless shock tube. Observations of double exposure holographic interferometry and pressure measurements at several points are carried out. The difference of shock wave attenuation over these models can be clarified.
