摘要 介绍了一种新的代数网格生成法———弧长法。该方法具有几何概念清晰、方法简单、计算迅速的特点 ,生成的网格贴体性好 ,收敛快 ,对复杂流场容易进行子块拼接 ,可以任意调节网格疏密程度。在网格生成的基础上对一算例迫击炮弹进行了N -S方程数值模拟 ,其结果符合气动特性规律 。 A new grid generation method-arc length method is introduced in this paper. This method has clear geometric conception.It is easy and quick to generate. The grid generated by this method can keep close to the body and can be converged quickly. It's easy to cohere with the complex flow field and can be easily adjusted to the spacing between grids. Based on the grid generated by this method, this paper has calculated a mortar with N-S equation.The results accord with the aerodynamic rules and mean that the grid generation is reasonable.
