Epsilon boundary condition for walls in LamBremhorst LowRe model
 

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.

Thanks

I am wondering how I can set nu.d2k / dy2= 0 in epsilon boundary condition.
