Comparative Analysis of Convective Heat Transfer Enhancement in Different Metal Ducts with Internal Threads

Abstract: The present paper focuses on Experimental analysis of heat transfer and experimental investigation of Heat Transfer enhancement through circular duct of aluminium and carbon steel using internal threads of pitch 5 mm and 10 mm with air as the working fluid. The experimental data obtained were compared with those obtained from plain duct.The effects of internal threads of varying depth on heat transfer and friction factor were presented for different metal (aluminium and carbon steel) as test metals. The heat transfer coefficient enhancement for internal threads is higher than that for plain duct for a given Reynolds number. The use of internal threads improved the performance of circular duct. Keywords: compare heat transfer enhancement, carbon steel duct, and internal threads.
