| 摘 要： | 利用多重拼接网格技术对三种不同类型的计算外形进行了内外流场的数值模拟,并将计算结果与单重对接和单重拼接的结果进行了对比,计算结果表明多重拼接网格技术在没有降低计算精度的情况下,大大简化了网格生成,同时可以把计算速度提高一个量级左右,取得了令人满意的效果。

| Abstract: | This paper presents the application for cross-multigrd technology.The inner and outer flowfiled of three kinds of computational figure have been simulated with the help of this method,and the computational results have been compared with results of single-patch grid and single-cross grid.It is shown by the results that this technology can remarkably predigest the process of grid generation and improve the convergence rate about 10 times than before without the decrease of computational precision,and the work in this paper established a good base for the future deep research. |
