摘　　要：针对可压缩流动问题,在开源CFD程序OpenFOAM上开发相应的求解程序.采用绝对坐标系下的Favre平均Navier-Stokes控制方程组和标准k-ε湍流模型.数值计算时,对流项和扩散项分别采用二阶精度TVD格式和二阶中心差分离散,求解离散后的方程组采用SIMPLER算法.通过对不同的马赫数下凸包流动和带有湍流模型的平面叶栅流动的计算表明,程序能够有效地模拟可压缩流动的流场.Based on the open source computational fluid dynamics（CFD） program OpenFOAM,the simulation program of a compressible flow field was developed.A Favre averaged Navier-Stokes control equation in an absolute coordinate system and a standard turbulence model were used.In numerical calculation,the convection term and diffusion term were discretized using a second-order accurate total variation diminishing（TVD） scheme and a second-order central-difference scheme respectively,and then the discretized equations were solved using the SIMPLER（semi-implicit method for pressure-linked equations-revised） method.Results were presented for hump flow through a channel at various Mach numbers and two-dimensional lattice flow with turbulence showing that the program can be effectively used in numerical simulation of a compressible flow field.
