Evaluation of engineering turbulence models for complex supersonic flows

  • 摘要: 对8°,16°,20°,24°超声速二维压缩拐角进行了数值模拟,系统评估了SA(Spalart-Allmaras), k-ω, SST(Shear Stress Transport)3种工程常用湍流模型对激波/边界层干扰复杂流动的模拟适用能力.对于"弱"干扰、小分离,工程常用湍流模型能够较准确地预测其压力、摩擦力、热流分布,而对于"强"干扰、大分离则会造成较大的偏差.同时,随着分离区的增大,各湍流模型的适用性能差别更加明显,数值方法也有一定的影响.
