Abstract

Abstract:

Turbulent flow and heat transfer in a channel with two parallel porous walls are reported. The Darcy-Brinkman-Forcheimer (DBF) acting model based on volume averaged hypothesis is added to the Navier-Stokes equation to simulate the flow bounded by porous media. The effects of porosity and Darcy numbers on skin-friction drag as well as Nusselt numbers are studied. The results on statistical quantities for flow field and temperature field show that the skin-friction drag decreases as the porosity becomes larger, and the Nusselt numbers may increase leading to enhancement of heat transfer efficiency when the Darcy number increases.

Key words: porous media, wall-bounded turbulence, drag reduction, heat transfer
