Research into impact effect on 3-D object of shock wave passing through curved channel and surrounding hill

The flow field of shock wave passing through curved channel and surrounding hill is investigated in a shock tube by holographic interferometry along with the quantitative measurement of the pressure distribution on the 3D object by transducer pressure measurement technology. The test results indicate that the effect in the flow field of shock wave is the largest at the copulation of 3D object and hill, the object leeward surface and its corner. It is significant to research into impact effect of shock wave at the complicated landform.
