Abstract

Numerical simulation was performed using an adaptive mesh refinement algorithm combined with a high resolution upwind scheme to study shock wave diffraction phenomena. The particular flow in interest is the shock wave diffraction over a 90 degree sharp corner in which the generation of a vortex at the corner and its associated shock waves are expected. The numerical results of the Euler computation show detailed structures of the flowfleld such as growth of Kelvin-Helmholtz instability along the spiraling sheet of the corner vortex and the interaction of the rolled-up vortices with the shock waves, so called “vortex shocks” inherent in the corner vortex.
