Underlying RANS model: v2f Standard k epsilon EBRSM 2-velocity Hybrid v2f/LES SSG-OMEGA DRSM Spalart-Allmaras (orig.) k-w SST N/A
if the model does not appear in the drop down list, please first add it in the turbulence model hub The methodology essentially consist into using WJ-EARSM-Hellsten as a subgrid scale model for LES in the regions where the grid resolution is sufficiently fine, while URANS is employed in the rest of the domain. The switch between URANS and LES zones is determined using the so-called DES length scale, defined to be the minimum between the characteristic URANS length scale and a length related to the local grid, times an appropriate scaling coefficient. It is worth to note that by this formulation, in LES regions the ω-equation has no influence, so that SGS model reduces effectively to a one-equation model.
