Abstract

To provide accurate numerical solutions for selected supersonic/hypersonic flow fields and to compare and evaluate the performance of selected turbulence models with experimental results, four popular turbulence models were tested and validated against experimental data of two turbulent flows. The investigated flows are 2D supersonic expansion-compression corner and hypersonic double ellipsoid. The tested turbulent models were: zero-equation model of Baldwin-Lomax(BL), one-equation model of Spalart-Allmaras(SA), two-equation k-ω/k-ε shear-stress transport(SST) model of Menter and two-equation k-ω model of Wilcox. It shows that the formal turbulent models are competent for the present supersonic flows. However, the simulation of the hypersonic flow, especially for flows at high angle of attack, compressibility modification is needed.
