Abstract: Numerical mean shear rate, volume mean shear rate and viscosity mean shear rate have been derived for power-law fluid flow through porous media.Physical meaning of some shear rate expressions has been analyzed.Different shear rate expressions should be used in different cases.Viscosity mean shear rate taking account of permeability reduction should be used in calculating viscosity of polymer solution(aqueous phase)for numerical simulation of polymer flooding.
