摘　　要：将空间－时间守恒（ＳＴＣ）格式应用于求解Ｎ－Ｓ方程，并对激波－边界层相互作用问题进行了计算．结果表明，该方法可捕获激波与边界层相互作用的各种现象，显示了优良的数值模拟性能。The space-time conservation (STC) scheme developed in Refs.6 and 8 is improvedto solve the two-dimensional interaction of the shock wave and the boundary layer. Fromits comparison with the experiment and the numerical results from the other methods it isconcluded:1. The STC scheme for solving a viscous flow can capture the shocks, the expansionwaves, and the separation of flow caused by the interaction of the shock and the boundarylayer. It is a useful method to calculate the Navier-Stokes equations.2. The construction of the conservation element and the related correction terms proposed in this paper may improve the numerical dissipation of STC scheme.
