dc.description.abstractLarge eddy simulations (LES) of wall resolved flows at high Reynolds number are still computation-ally demanding. In the present work, a new Dynamic Wall Model (DWM) for LES is presented. The methodology, implemented on unstructured meshes and formulated in a general form, takes into account non-equilibrium effects. The DWM is validated with a channel flow at Ret = 4200 by comparing with direct numerical simulation (DNS) from literature. Once the model is verified, it is used to simulate the flow around a wind turbine dedicated airfoil (DU-93-W-210) in stall condition at Re = 3 × 106. Numerical results shows that the current DWM strategy is capable of accurately capturing the flow detachment and transition to turbulence.
