Formular in wallShearStress tool?
 

Hello Foamers,

can anyone give me some references where to find the exact derivation of the formular used in wallShearSress tool? I read a lot of books, but i could not find it.

Furhtermore, can anyone tell me if this formular is also valid for two-phase-flows, i.e. VOF?

Cheers in advance!
