摘　　要：ＳＴＣ格式是一种求解积分形式物理守恒律的计算方法，具有守恒性好，精度高的特点。目前求解Ｅｕｌｅｒ方程的ＳＴＣ格式已经建立起来，但求解Ｎ－Ｓ方程的ＳＴＣ格式尚在发展之中。为了使ＳＴＣ格式能够有效地求解粘性流动的问题，本文构造出了求解曲线坐标系下的二维Ｎ－Ｓ方程的二阶ＳＴＣ格式。用该格式对跨音速湍流流动问题进行了计算。The STC scheme is used to solve the integral equations of conservation laws. It has the properties of conservation and high accuracy. The STC scheme for solving Euler equations has been constructed, but the scheme for solving N-S equations is being developed. In order to make the STC scheme an effective tool in numerical simulation of the viscous flow, the second- order STC scheme for solving two dimensional N-S equations in nonorthogonal curvilinear coordinates is constructed in this paper. The transonic t...
