wall function and flow separation

O.D.Y. · November 15, 2009, 06:40

Hi @ all,

I'm wondering if it is possible to calculate flow separation with wall functions?

I have a problem where separation occurs when resolving the boundary layer.... I used wall functions afterwards and the separation is still there.

As far as I can see, the separation is induced by the pressure gradient.
Does anybody know if wall functions are also able to resolve flow separation due to viscosity effects?

see section 4.6.2 in turbulence modeling for cfd by wilcox.you will find your answer
