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 |
