Three-Dimensional Adaptive Unstructured Mesh for Euler Equations
Zhu Pei · 2002
The threedimensional Euler equations are solved on unstructured tetrahedral meshes using an adaptive strategy. The basic algorithm for the Euler solver consists of an explicit vertexbased finite volume method. The Delaunay triangulation is used both to generate the meshes and to refine the meshes. The transonic flow over the ONERA M6 wing is calculated by means of the adaptive strategy, and the results are compared with experimental data to show the accuracy and efficiency of the present method.
