dc.descriptionA porous medium are materials consisting of a solid material with an interconnected void allows the fluids flow through the voids, have considerable importance in improvement of heat storage and heat transfer. The present work is the simulation of steady state flow and heat transfer through porous media inside pipe which considered as a fixed bed used for heat removal by using COMSOL Multiphysics (05) software for two models Darcy model and non- Darcy model (Brinkman model) to investigate numerically the effects of Reynolds Number , Porosity and porous media thermal conductivity. The analysis was carried out under the assumptions of, Newtonian, constant fluid properties and steady fully developed laminar flow for the thermal problem, a uniform wall heat flux boundary condition (150W/m²) for all study stages and same inlet temperature , The calculations were made using a steady state , two-dimensional rectangular geometry for both models, In the first stage the spherical particles thermal conductivity (1.26 W/m.K) and the porosity value (0.39).the simulation had been done for various values of Reynolds Number [0.01,0.05,0.1,0.5,1&5] for Darcy model and [30 , 50 , 70 & 90] for Brinkman model. In the second stage the porosity values were [0.39,0.42 &0.47] ,the Reynolds Number 1 for Darcy model and 90 for Brinkman model , thermal conductivity (1.26 W/m.K) , The last stage had been done for various values of thermal conductivity [1.26,10&19W/m.K] when Reynolds Number(01) for Darcy mode,(90)for Brinkman model and the porosity (0.47),[Carmen-Kozeny equation was used to determine the permeability of the packed bed and Furnas equation for porosity] The results showed that the outlet temperature depends greatly on Reynolds Number values, that mean it´s decreases when Reynolds Number increases, the heat transfer coefficient , Nusselt Number and pressure drop increase when Reynolds Number increases , but when the porosity values increase the outlet temperature increases and the pressure drop decreases.
