内容記述 | A grid adaptation method using anisotropic Cartesian grid in three dimensions has been developed to improve the efficiency of an existing Cartesian grid adaptation by reducing the total number of cells needed to resolve flow features. The method is capable of coarsening and refining a grid in such a way that the cell aspect ratio can take an arbitrary value. Flow computations with the present method for a supersonic flow around a cylinder and a transonic flow around an ONERA M6 wing are presented here, which show good agreement with experiment. For the case of cylinder, the present method produces about 67 times fewer cells than the isotropic approach. This dramatic saving is due to the ability of the three-dimensional code employed here to treat cells without any limitation on their aspect ratio. For the case of ONERA M6, the ratio of saving is about 2.5. Though the amount of memory per cell is higher than that of the isotropic approach, the overall memory requirement becomes lower, due to reduction in the number of cells. This means that the present method can make flow computation more efficient. | |||||
