Applications on Hybrid Unstructured Moving Grid Method for Three-Dimensional Compressible Flows

摘要

For CFD problem with a complicated moving boundary, the unstructured moving-grid finite-volume method has been proposed and its ability recognized. However, the method was limited for applications using inviscid compressible flows. In this paper, the method is developed to apply to three-dimensional Navier-Stokes equations for viscous compressible flows. We formulate a control volume for prismatic element well adapted to unstructured mesh. Then, the method is applied to a flow around oscillating ONERA M6 airfoil at high Reynolds nmber. And the computation is executed in OpenMP parallel environment.
