Abstract

Two-dimensional forced convective flows in micro-sized porous media composed of periodical arrays of square rods or cylinders were numerically investigated at the pore scale. For the permeability calculations, both volume averaging technique and multiple scale expansion technique were employed, and the results compared. The effective thermal conductivity was calculated from computations carried out at the microscopic level and then used in macroscopic models for local thermal equilibrium condition. In the range of parameters investigated, good agreements between the microscopic and macroscopic predictions are shown
