A note on the existence for a model of turbulent flows through porous media

Abstract

In this work, turbulent flows through porous media are considered. We begin by making a historical review of the equations governing laminar flows in porous media, from Darcy’s law to Darcy–Brinkman–Forchheimer’s more general model. Using the double averaging concept (in time and in space) we explain how to obtain the more general system of equations that governs turbulent flows through porous media. For the one-equation turbulent problem in the steady-state we show that the known existence results can be generalized to any space dimension d ≥ 2 and for a more general function of turbulence production.
