Abstract: The present paper focuses on Experimental analysis of heat transfer and experimental investigation of Heat Transfer enhancement through circular duct of carbon steel using internal threads of pitch 5 mm and 10 mm with air as the working fluid. The transitional flow regime is selected for this study with the Reynolds number range 7,000 to 14,000. The duct was subjected to constant and uniform heat flux. 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. Based on the same pumping power consumption, the duct with internal threads possesses the highest performance factors for turbulent flow. 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: heat transfer enhancement, carbon steel duct, internal threads.
