Wall fonction
Hi..
I work with turbulent natural convection flow of air in the square cavity with differentially heated vertical side walls. I use the following wall fonction for turbulent variables: K=0. at the wall Epsilon=Cte (K^(3/2))/l at the first inner grid point with l the closest distance to wall I use Cte=0.4 is it true??? or may I use an other value??? Thanks for your help

Hi,
The constants in Kepsilon model are not the same for all flows.I suggest you look for relacted flows in square cavities. Valdemir. 
QUICK or CUI is third order?
Hi, I consider well known van Leer class of the kscheme: phi_f=phi_C+(1/4){(1+k)(phi_D  phi_C)+(1k)(phi_Cphi_U)}. In many papers it is written that setting k = 1/3 we receive the scheme of the 3rd order (socalled CUI scheme), but I receive the 3rd order only at k = 1/2 (i.e. QUICKscheme). Where can be an error?
