effective viscosity
hi to all.

i am modelling a porous domain.and i want to know how ansys cfx calculate the effective viscosity

is there any relation to calculate it manully?

eddy viscosity + laminar viscosity

This is all described in the documentation, and if that is not good enough try a turbulence modelling text like "Turbulence Modelling for CFD" by Wilcox.

thanks for your reply.this is not what you porous region and porous equation always an effective viscosity is differs from "laminar+turbulent viscosity".
