| 摘要: |
| 本文在用椭圆型方程的网格生成方法生成曲线网格时，通过比较四种常用的计算格式，得到了收敛速度较快的生成方法。在计算流体力学领域，对于边界形状随时间变化的流动问题的数值计算，及自适应网格的生成等问题，生成网格的收敛速度直接影响流场的计算速度。在上述情况下使用本文的结果，能有效的减少机时，提高计算效率。 |

| Abstract: |
| In this paper，the grid generation techniques of elliptic equation are employed to generate curvilinear grids and the best difference scheme is obtained which allows fast convergence in numerical calculation by comparing four commonly used schemes. The conclusion is useful to the numerical calculation of flow，and the boundary shape is dependent on time and the adaptive grid generation. |
