Abstract

We investigate the flow through a porous medium both numerically and experimentally. The computer simulation solves a generalized non-linear extension to Darcy's law, known as Darcy-Brinkman-Lapwood-Forchheimer (DBLF) equation in a way that allows us to estimate the significance of each term in this equation. The numerical results have been validated against tracer transport data obtained using positron emission tomography (PET), a novel, non-invasive technique for flow-visualization. The results indicate that viscous diffusion is of significance over a narrow region, "the Brinkman-layer", below the fluid-sediment interface, and that the Darcy equation alone is not sufficient to estimate the advective transport correctly.
