title = "Detached Eddy Simulation on the Flow Around NACA0021 Airfoil Beyond Stall Using OpenFOAM",
abstract = "Accurate simulation of high Reynolds number flow around airfoils beyond stall is a challenging computational fluid dynamics (CFD) problem of significant importance in aerospace industry. In this study, detached eddy simulations (DES) have been performed on the flow around NACA0021 airfoil beyond stall at 60° angle of attack. Detailed investigations are carried on the effect of time step, the effect of span-wise length and the effect of grid resolution, respectively. The present DES results show good agreements with the experimental data and some other published pioneering work. The DES model in OpenFOAM shows a good capacity in the prediction of unsteady flow with separation and vortex shedding. Compared to the unsteady Reynolds-averaged Navier-Stokes (URANS) simulation, DES simulations show visible improvements on the prediction of force coefficients and the flow structures.",
