BC for epsilon in NaganoTagawa k-epsilon model
 

Hi all,
I am implementing Nagano-Tagawa's k-epsilon model in OpenFOAM.

As mentioned in this site :: http://www.cfd-online.com/Wiki/Low-Re_k-epsilon_models , i believe it requires us to set the boundary condition for epsilon at the wall which is usually set to 0 for Launder-Sharma's case.

Could anyone kindly explain how do I employ that boundary condition for epsilon at the wall in OpenFOAM???

Any help is highly appreciated.

Thanks
Nikesh.
