Abstract
If the resolution of the computational analyses is fine enough to compute accurately the deformation of the velocity field but not fine enough to resolve the boundary layer, the k − ε model is used accomplished with special treatment of the boundary conditions. In such case in general the deformation term is non-negative, \(\overline{P_{k,l}}\geq 0\) and the porous body source terms are set to zero P kw,l = 0, P εw,l = 0.
