【摘要】 前言U前可用于工程应用的各种紊流模型中，在对逆压梯度下有无分离流动、低雷诺数区域流动以及对可压缩流动，特别是高速紊流流动等问题的精确数值模拟上，除多重尺度模型外，预测精度较理想的是k一。两方程模型。在k一。模型的开发和应用上，Wilcox及Menter等［‘－’］?..更多还原

【Abstract】 In the present paper, a compressible k-ωturbulence model was developed for simulation of high speeds flows. In the model, effects of dissipation and pressure expansion due to compressibility were taken into account. Coupled with the present turbulence model, the 3D Reynolds-averaged Navier-Stokes equations were solved for the transonic and supersonic flows inside nozzles and cascades.更多还原
