Enhancing Heat Transfer in Porous Media Systems through Finned Cylinders: An Experimental Investigation

Abstract

The present study shows finned cylinders increase porous medium heat transport. To promote heat dissipation, a porous material region with air-carrying tubes and internal heating devices evaluates different tube shapes and fin patterns. A study found that fins increase thermal exchange surface area, improving heat transfer. Additionally, staggered tube layouts function better than in-line ones. Fluid velocity, or Reynolds number, affects convective heat transfer efficiency, especially with fins. Comparing experimental methods and outcomes to previous studies proves reliability. The work gives us insights into heat transfer in porous materials and enhances industrial thermal management systems. Fins boost heat transmission by 55% in-line and 26% in staggered structures at a fixed Reynolds number. At low heat flux, the fins improve heat transfer by 71% for in-line designs and 139% for staggered designs. High heat flux reduces efficacy.
