Question regarding k-omega model
 

Hello All;

I have a question regarding the wall boundary condition for k-omega model.

How the Turbulent Kinetic Energy (TKE) as well as the frequency (w or omega) are solved at the first grid node? I was learned that k is obtained the same way using k-epsilon model (fluent 2003) (i.e. modifying the generation term and solve the transport equation at the first node, and epsilon is specified at the first node). I tried that but the results do not look reasonable, something is going wrong.

Please kindly advice.
