| 摘 要： | 贴体曲线网格的自动生成是弹丸绕流流场数值模拟技术的重要组成部分.本文采用Thompson任意曲线网格生成方法和非齐次离散源项,研究了弹丸流场求解域的网格生成问题.实际的流场计算表明,用这种方法生成的曲线网格,完全满足弹丸绕流流场Navier-Stokes方程数值模拟的需要.

| Abstract: | The boundary-fitted grid generation is an important part of numerical simulationtechnology of projectile flowfield.In the present paper,the grid generation of computationaldomain of a projectile was studied,using Thompson Boundary-fitted Grid Generation Methodand a discrete nonhomogeneous source term.It shows that,the gird generated using the presentmethod satisfies the Navier-Stokes computations of projectile flowfield completely. |
