The heat/mass transfer characteristics of a porous medium in two and three-dimensions are investigated by using the Lattice Boltzmann Method to analyze the ball packed-bed regenerator of reheating furnace in steel rolling process. To obtain the bulk properties of the porous medium of various structures, calculations have been performed for porous media of regularly distributed inclusions.. It is found that the thermal dispersion is influenced by the medium structures, the Peclet number, the volume fraction of the solid, the thermal conductivity ratio of the solid and the fluid, and the Reynolds number. The streamwise thermal dispersion coefficients increase with the Peclet number, the volume fraction of the solid, the Reynolds number, and the thermal conductivity ratio of the fluid to the solid. The parameter that affects the thermal dispersion most is the Peclet number
