基于可压缩Navier-Stokes方程,采用Beam-Warming矢通量分裂格式以及vanLeer的矢通量分裂方法,分别通过Johnson-King及Baldwin-Lomax湍流模型对亚音速和超音速的后台阶流进行了计算,计算结果与实验符合较好。
Based on the compressible Navier-Stokes equations, subsonic and supersonic backstepping flows were calculated using the Beam-Warming vector flux splitting scheme and the van Leer vector flux splitting method respectively using the Johnson-King and Baldwin-Lomax turbulence models , The calculated results are in good agreement with the experiment.
