N2 - High Reynolds number flows around airfoils involve complex phenomena at different angles of attack (AOA). In this study, improved delayed detached eddy simulations (IDDES) are carried to investigate the flows around S809 airfoil at a wide range of AOA from 0 to 90 degrees. In addition, unsteady Reynolds-averaged Navier-Stokes simulations (URANS) are adopted for a comparison purpose. Both IDDES and URANS simulations agree well with the experimental results in the attached flow regime of low AOA. However, in the mild separation and massive separation regime, IDDES simulations show better prediction than the URANS simulations. Detailed flow structures are analyzed with comparisons between IDDES and URANS simulations.
