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。
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.
