A Comparison of Two Dynamic Mesh Methods in Fluid-Structure Interaction

摘要：

　　Two dynamic mesh methods— Radial Ba sis Function (RBF) method and Delaunay method which have been used widely in fluid-streture interaction recently were compared.Primarily,the basic theory of these two methods and the dynamic mesh process were presented.Furtherm ore,using the variable bandwidth sparse matrix storage technique,the corn putational efficiency of the RBF method can be im proved.Taking ONERA M6 wing as an exam ple,the mesh quality and computation time of the mesh motion after the airfoil rotation and wing deformation were checked.The results show that RBF method generate a better quality mesh in both structure and unstructured mesh while Delaunay method performed high efficiency,especially when the node num bet of the wing surface is large.
