A macroscopically uniform flow is assumed to pass through a porous medium made of two-dimensional periodic arrangement of circular rods placed in an infinite space. By exploiting the periodicity of the porous structure, only one structural unit has been taken as a calculation domain. Extensive numerical calculations were carried out using a finite volume method (SIMPLE) to describe the microscopic velocity and temperature fields at a pore scale. The thus-obtained microscopic numerical results were proposed to extract the macroscopic characteristics in terms of the volume-averaged quantities. Integrated parameters such as macroscopic pressure gradient, thermal dispersion, and interfacial convective heat transfer coefficient were evaluated for a wide range of porosity and Reynolds numbers. The proposed correlations agree well with available numerical and experimental data. %8 2008-02-21
