Assessment of Linear Eddy-Viscosity Turbulence Models in Shock/Boundary-Layer Interaction

摘要: 本文选择了两个激波 /边界层相互作用诱导分离的跨声速问题 (轴对称圆弧突起和二维管道突起), 采用五个有代表性的湍流模式 (BL模式, JL k-ε模式, k-ω模式, SST模式和双尺度模式), 通过将数值计算结果和实验结果进行比较。

Abstract: Five popular turbulence models have been tested and validated against experimental data of two turbulent flows.The models are:(1)the zero equation model of Baldwin Lomax;(2)the two equation k ε model of Jones and Launder;(3)the two equation k ω model of Wilcox;(4)the two equation k ω/k ε SST model of Menter;(5)the two scale k ε model.The benchmark flows are two transonic flows over bump geometries with shock wave/boundary layer interaction including separation.The computational results demonstrate that the SST model yields superior performance and the zero equation turbulence model does not provide satisfactory results. -
