| Abstract: | 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. |
