Dear Foamers,

Could anyone tell me the boundary condition for epsilon when we use LamBremhorst Turb model. The literature says there are two types of LB model . The change is only with BC for epsilon at walls.
1. Setting zero gradient for epsilon
2. Setting (nu. d2k/dy2 ) = 0

I presume k can be set as very low value at the wall and nut (turb viscosity) as zero gradient.

If anyone can shed some light it would be useful.
