摘要

摘要: Turbulent flows over AS240 and NACA4412 airfoil were simulated numerically using a two-equation turbulence model named k-ξ model. The predictions of velocity profiles and the pressure coefficient of airfoil AS240 at 8°/19° attack angle and NACA4412 at 13.87° attack angle were calculated. The results were compared with those using k-ε and k-ω models,as well as experimental data. It indicates that the new k-ξ model offers more realistic prediction than the other two models. The main finding shows that the new k-ξ model is good at predicting separated flows around airfoils, and it captures the flow feature of pressure-induced separation adequately. All calculations are implemented as per openFOAM 1.7.1(open source field operation and manipulation).
