Nowadays, Large Eddy Simulations (LES) calculations are still prohibitively expensive at high Reynolds Number, specially for aerodynamic applications where wall flows are present. Different strategies can be found in the literature in order to reduce mesh requirements at the near-wall region such as hybrid Reynolds Averaged Navier Stokes (RANS)/LES approach or Wall Functions. Dynamic wall models in which this paper is focused, are part of these strategies. The present model is intended to make f...
