Investigations on the Flow Fields of Hypersonic Flow Past the Wall-Mounted Square Cylinder with Various Heights

Abstract

Combined with the large eddy simulation (LES), a 3rd-order WENO scheme and the adaptive mesh refinement (AMR) technique, the hypersonic compressible flow (Ma ¼ 5) past wall-mounted square cylinders with different heights is simulated numerically. Our results reveal that with the variation of cylinder heights, the pressure distributions of the flat plane in front of the cylinder are similar and have multiple peaks. The different flow patterns of the flow field around the cylinders are shown and discussed in detail. Our calculated results are in good agreement with corresponding experimental data which can provide important data for related research.
