RENORMALIZATION GROUP ANALYSIS OF THE STABILITY OF TURBULENT FLOWS IN POROUS MEDIA

The concept of renormalization groups for modeling the parameters of flow in porous media is considered. An algorithm for the renormalization of the equations from the k–ε model of turbulence is given. An expression is obtained for the coeffi cient of renormalized viscosity. Based on the model developed, conditions of the turbulent flow instability in a porous medium have been analyzed.
