Thank you for your explanation, Roman.

In Openfoam, when we use wall function for both RANS and LES, the velocity at the walls are zero. So here the non-slip velocity is still applied. Can the...

Dear Roman,

Thank you for your reply. In the practical CFD implementations, if we use cell centered finite volume method as is done in the OF, the velocity gradient is needed to calculate the...

Hi All,

I have a question about the wall functions implemented in Openfoam. Theoretically, when wall function is used, the velocity at the wall is not zero and instead the velocity there is the...
