摘要: 应用4 个多尺度涡粘性湍流模式对一个二维压缩拐角流动进行了数值模拟,通过与实验结果以及两个基准模式(一个单尺度k-ε两方程模式和一个零方程模式) 的计算结果的比较,结合压缩性对湍能输运的作用、湍流的非平衡性对多尺度湍流模式在拐角非平衡湍流中的应用进行了评估。

Abstract: Four multiple-scale turbulence models and two baseline models are applied to simulate the flows over a series of two-dimensional compression corners. Comparisons are made and assessment of the models are performed withdiscussions of compressibility and its effect on nonequilibrium energy transfer. It’s shown that the treatment of multiple scaling is efficient and potential.
