the value of k in near wall cell?? is not consistent with wall function?

qi.yang@polimi.it · April 20, 2020, 12:36

Hi guys,

I verified the k value in near wall cell with the formulation of k in boundary layer (Utau^2/sqrtCu) and I found they are not consistent with each other. I am confused that kqrwallfunction is applied at the wall for k, which is similar to zerogradient condition. I did not find the code how to calculate the value in near wall cell. Do you have any ideas about this issue?

Many thanks,

Is there anybody can give me some explaination?
