Abstract
Fluid flow through porous media consisting of randomly-generated mono- and binary-sized spherical particles is investigated using the lattice Boltzmann (LB) method. The effects of porosity, particle mean diameter and diameter ratio, and Reynolds number on velocity and drag force distribution in porous media are investigated. Based on the numerical results, a more accurate equation for calculation of the mean drag force in particulate porous media is proposed. Probability density distributions of velocity in pore space and drag force on individual particles are investigated and the range of variations according to the mean drag force is introduced. The results suggest that porosity and Reynolds number in mono-sized domain have the most significant effect on the mean drag force; in binary-sized domain, however, the size ratio has a significant effect.
