Shock Wave Diffraction around Circular Cylinder Using Unstructured Adaptive Meshes

摘要

The study of flow around a circular cylinder is one of the most important problems in not only basic research but also analysis of a complexity object. No numerical simulation of shock wave diffraction around circular cylinder has been carried out thus far. Under supersonic flow in particu- lar, the numerical result is insufficient for the lack of resolution in the complicated flow around passing through circular cylinder. Therefore, we used unstructured adaptive meshes which can automatically divide elements only in the region of large variation.
