Enhanced Rate of Heat Transfer through Periodic Triangular Array of Circular Cylinders Embedded in Porous Media

Abstract

Heat transfer enhancement through porous media are of interest in many thermal applications. Forced convection through a triangular array of circular cylinders embedded in a fluid-saturated porous media has been investigated using extended Darcy Brinkman-Forchheimer momentum equations and Local Thermal Equilibrium (LTE) model. Detailed results are illustrated, for high permeability levels (Darcy number varied from 1/10³ to 1/10) and different cylinder spacings (0.7 ≤ φ ≤ 0.99) at Re = 100. It is anticipated that porous media would enhance heat transfer, but it emanates multiple order in pressure drop.
