CONVECTIVE HEAT TRANSFER AND FLUID FLOW ANALYSIS IN A HELICAL MICROCHANNEL FILLED WITH A POROUS MEDIUM
要約
Forced convection in a helical microchannel heat sink (HMCHS) filled with a porous medium is investigated numerically. The effects of helix radius (0.15−0.30 mm), pitch (0.5−2.0 mm), number of turns (7−10), and aspect ratio (1.5−3.0), toward the heat transfer and fluid flow characteristics are comprehensively investigated. The governing equations for flow and heat transfer are solved using the finite volume method. The results reveal that secondary flow and porous medium can enhance the thermal performance of the HMCHS but is accompanied with an increase in pressure drop.
