Solution of Euler Equations on the Two Dimentional Unstructured Grids

Yin Xingyu\ Wu Zhilei\ Zhu Ziqiang (Beijing University of Aeronautics and Astronautics,Dept.of Flight Vehicle Design and Applied Mechanics)  
Both Delaunay triangulation method and advancing layers method for generation of unstructured grid are discussed.A combination of both methods to form an unique method,i.e.,the background grid is generated by using Delaunay method and space computational grid over the whole flow field is generated by advancing front method,is suggested in the present paper.The new approach improves the quality of grid and efficiency of the computation.The Euler equations on unstructured grid are solved by cell center scheme of finite volume method.Numerical examples show that the corelation of the computational results with experimental data is favorable and the needs of N S equation solver is obvious for both case of airfoil in transonic flow and multi element airfoil in subsonic flow.
