Effect of Thickness of Porous Layer on Thermo-Hydraulic Characteristics and Entropy Generation in a Partially Porous Wavy Channel

Abstract

The present study discusses the effect of thickness of porous layer, Reynolds number and Darcy number on the thermo-hydraulic transport and entropy generation characteristics for flow through a partially porous wavy channel. The walls of the channel are heated under constant heat flux conditions. Brinkman–Forchhemier model has been employed to model the porous medium. The results reveal that the average Nusselt number and pressure drop increase with the thickness of porous layer and Darcy number. It is observed that the entropy generation decreases with the increase in Darcy number and thickness of porous layer.
