The purpose of this paper is to present a numerical methodology for simulating the flow of shock tunnel . the numerical approach uses a maccormack scheme or s - w spiliter for the quasi - one - dimensional euler equation coupled with real gas effect . a simple method is used to track contact discontinuities 采用maccormack格式及s - w分裂方法求解准一维euler方程，考虑高温下分子的振动、气体和壁面间的摩擦和传热，根据高压段的气体质量守恒的方法来跟踪接触间断。
