1 Wall Treatment

The LES wall function in OpenFOAM assumes an instantaneous correlation between the the velocity at the first off-the-wall grid point and the wall shear using an assumed velocity distribution (usually done). In the particular case of OpenFOAM, the Spalding's continuous law is used.

One can find the implementation in src/turbulenceModels/LES/incompressible/wallFunc/nuSgsWallFunction
