Abstract
Shock wave propagation through an inclined inhomogeneity is investigated experimentally and numerically. The shock wave is generated by exploding wire technique, and its propagation is captured using shadowgraph technique. The numerical simulation is performed using an in-house code. When a shock wave encounters such a medium, the flow field is no longer symmetric. The transmitted shock rotates itself to travel along the inclination axis, the precursor regions are relatively elongated, and the baroclinicity-induced vortices are skewed with respect to the inclination axis. This study also explores the possibility of using the inhomogeneity as wave guides.
