| Abstract: | A grid reconstruction algorithm based on two-dimension unstructured grid is introduced. The cellvertex finite volume method is used to dicretized Euler equation and the Roe Flux-Difference Splitting method is used to calculate the flux. The LU-SGS method is used for time accurate. The numerical solutations of flows around NACA0012 airfoil and RAE2822 airfoil are calculated with present method, which show that the method works well and has a high efficiency. |
