| 摘 要： | 给出ＴＶＤ格式的构造过程，特别地，构造了两维任意曲线坐标系下欧拉方程组的ＴＶＤ格式，并结合四阶Ｒｕｎｇｅ－Ｋｕｔｔａ法求解超音含激波流场，文中对边界条件提出了一种很好的处理方法，数值计算表明，ＴＶＤ格式是求解强间断流场的行之有效的方法，文中的处理方法易于提高解的精度和加快解的收敛性。

| Abstract: | In this paper,TVD scheme, especially the scheme of Euler equathnsions in 2-D generalnon-orthogonal coordinates has been constructed. Four-Stage Runge-Kutta technique and akind of new boundary conditions based on upwind difference scheme have been used to com-pute supersonic flow field. The numerical results show that the scheme and techniques canimprove numerical stability and enhance its efficiency. |
