Abstract
In this study we revisit Schardin's problem by investigating experimentally shock waves diffract- ing over a finite wedge and interacting with the tip vortices in a complicated manner. Holographic inter- ferometry and shadowgraphy were used in a shock tube for a shock Mach number Ms =1 .34. Numerical simulations were carried out to obtain complementary flow data. The experimental results show that di- verging acoustic waves are generated due to the interaction between shock waves and vortexlets along the slip layer. By means of the computational results obtained for short time intervals, and the corresponding optical images, analysis of the shock-vortex interactions became possible for extended time periods.
