Abstract

Mesh generation is an important aspect in Computational Fluid Dynamics(CFD). Methods based on the structured and unstructured meshes both have their advantages and disadvantages. The best way is to combine them and adopt the benefits of both. The unstructured mesh which has shown the potential power to deal with the complex geometry will encounter problems in dealing with the viscous flow case. In this paper we first discuss some methods to generate both structured and unstructured meshes. An Euler flow solver with a cell-centered, finite-volume, Point-Gauss-Seidel implicit time-stepping scheme is validated on these two types of mesh topology. Then we propose a strategy, called the "SKIN" method, to construct a hybrid mesh based on structured and unstructured meshes. The Euler flow solver is then modified and applied on this type of hybrid mesh. Numerical tests demonstrate the efficiency of the hybrid mesh, generated by the present method, and the robustness of the particular Euler solver on different type of meshes.
