โœฆ Synopsis

An analytical study on fully developed forced convection in a homogeneous porous medium is presented. Closed form solutions for the temperature distributions in the transverse direction with the inclusion of frictional heating due to viscous dissipation are obtained, with variations of Darcy number and Brinkman number. The frictional heating effect on the temperature distributions is investigated and analyzed for both heating and cooling processes. Variations of Nusselt number as a function of Darcy number and Brinkman number are examined, and the deviations of the Nusselt numbers with that of the model without incorporating the effect of frictional heating are presented in a contour deviation map for a more holistic comparison.

This experimental study investigates non-Darcian flow and heat transfer in high-porosity fibrous media. It considers forced convection through materials of different permeability, porosity and thermal conductivity. The results show that the porous medium enhances heat transfer from a surface as comp
