| 摘 要： | 本文讨论用分区方法计算可压缩无粘流动的内边界通量守恒算法。分析指出插值型通量守恒算法不保证相容性条件,计算表明这种不相容性能引起数值解出现明显误差,或破坏其稳定性、收敛性。为此,文中提出内边界采用自适应算法并给出了算例。

| Abstract: | Conservative algorithms for internal interfaces are investigated for simulations of compressible inviscid flows by zonal methods. Analysis indicates that the conservative algorithm of interpolation type may be inconsistent with governing equations of the flows,and calculations show that this will cause severe numerical errors,and even ruin the stability and convergency of the computed solutions. Therefore, self-adaptive methods are proposed for internal interfaces and numerical examples are also presented. |

| Keywords: | compressible inviscid flow conservative algorithm for internal interface consistency self adaptive method |
