| 摘 要： | 以三维非结构网格的显式有限体积法为基础,采用了一种TVD方法求解三维Euler方程,使用Roe通量来计算网格单元边界处的守恒量通量.为了验证方法的可行性,用该方法模拟三维爆炸问题,得出的结论是我们的方法可行,稳定且有效.

| Abstract: | We use a finite volume TVD method for solving three-dimensional Euler equations in the basis of unstructure grids,and we use Roe flux for computing the conservation of flux.In order to verifying our method,we solve the three-dimensional explosion test program.we come to the conclusion that our approach is viable,stable and effective. |
