An Experimental, Numerical, and CFD Investigation into the Heat Transfer and Flow Characteristics in Porous Media Using a Thermal Non-Equilibrium Model

Abstract

Heat transfer and fluid flow through porous media was investigated using numerical simulations and experiment. For the numerical simulations, two models were created. The first consisted of a two-dimensional numerical model created in MathCAD and was solved using the finite difference approach. The MathCAD model's flow in the porous media was described by the Brinkman-Forchheimer-extended Darcy equation. The second model consisted of a computational fluid dynamics (CFD) porous media model using Fluent and was solved using the finite volume approach. Both models assumed constant fluid phase and properties. Pore diameters were held constant for each simulation; two different porosities were investigated. Boundary conditions were applied at the wall in which the temperatures of the fluid and the porous media were determined by coupled energy equations. The effects of the boundary condition, the Reynolds number, porosity, and heat input were examined.
