Abstract
AbstractThe present study investigates, using the lattice Boltzmann method, the influence on the flow of the boundary condition at the open and porous medium interface for a two‐dimensional channel with half of the channel filled with a random porous medium. By simulating the fluid flow at pore level, the proposed macroscopic hydrodynamic boundary conditions are evaluated; correlations for the empirical constant in one of the most widely used models are also presented. The predicted values for the flow rate are in overall agreement with the previously published values. Copyright © 2007 John Wiley & Sons, Ltd.
