title = "Partially-averaged navier-stokes simulations of unsteady flow around NACA0021 airfoil at 60°angle of attack",
abstract = "The high Reynolds number flow around airfoils at large (beyond stall) angles of attack is a challenging CFD problem of significant importance for the aerospace industry. In this study, partially-averaged Navier-Stokes (PANS) simulations have been performed on the unsteady flow around a NACA0021 airfoil at 60°angle of attack. A spatially varying PANS model is modified and validated. Detailed investigations are carried on the effect of time stepping, the effect of span-wise length, the effect of grid resolution, respectively. The results show the best agreement with experimental data when ranges from 0.1 to 0.4. Compared to the unsteady Reynolds-averaged Navier-Stokes (URANS) simulation and the detached eddy simulation (DES), PANS simulation shows visible improvements on the prediction of force coefficients and pressure distribution on the surface of NACA0021 airfoil.",
