提出了使用雷诺平均纳维-斯托克斯方程和各种湍流模型对跨音速翼型流进行数值模拟，并与实验数据进行了比较。在从亚临界未分离流到超临界分离流的不同流动条件下研究了三种不同的翼型。研究的湍流模型由三个零方程模型和一个二方程模型组成。对于涉及弱粘性-非粘性相互作用的未分离流动，四个模型与实验的一致性相当。对于涉及强粘性-非粘性相互作用的分离流，Johnson 和 King 的非平衡零方程模型给出了与实验的最佳总体一致性。
Numerical simulations of transonic airfoil flows using the Reynolds-averaged Navier-Stokes equations and various turbulence models are presented and compared with experimental data. Three different airfoils were investigated under varying flow conditions ranging from subcritical unseparated flows to supercritical separated flows. The turbulence models investigated consisted of three zero-equation models and one two-equation model. For unseparated flows involving weak viscous-inviscid interactions, the four models were comparable in their agreement with experiment. For separated flows involving strong viscous-inviscid interactions, the nonequilibrium zero-equation model of Johnson and King gave the best overall agreement with experiment.
