The epsilon relation was indeed correct. The real problem was i always used paraview to visual the fluent results, for some reason data translation went...

Yes, yP is the cell center to boundary distance as by definition (half of the cell height in my case). The turbulent kinetic energy calculation is correct indeed. turbulent kinetic energy = Cmu *...

Dear Lucky, Sorry i forgot to mention that i used standard wall function. Since i had validation problems with enhanced wall function, i change it to standard k-epsilon model with standard wall...

What i was looking was a user specified boundary conditions (for all field variables) at the wall instead evaluating from wall functions. In this case, we do not...

Replies: 12 Low-Re turbulence Model without wall-functions Views: 2,915 Posted By bruce Low-Re turbulence Model without wall-functions Dear All, I am using Realizable k-epsilon low Re. turbulence model for a simple test case with y+~1-3. By default, the standard wall functions are selected in GUI. I want to disable all the wall...
