From what I understand about LES wall functions, in order to use nuSgsWallFunction you should have a y+ > 30 which places your first computational cell away from the wall within the inertial sublayer....
My question is... does the wall function take into account if you have a y+ < 30 (i.e. your grid is finer 'than necessary' near the wall)? Couldn't Spaldings law (which I understand is the assumption made for the nuSgsWallFunction) just be extended to adjacent cells up to those cells which have the value of y+ required?
Hope this question makes sense....
Also, what are the alternatives to this wall function in OpenFOAM?
Hope someone can help. Thanks for your time.
