Abstract
In present experimental analysis, the outer cylindrical tube of the ordinary concentric tube type heat exchanger was replaced by conical tube. New conical tubes of different diameter ratios have been developed by using epoxy resin and glass fiber. Diameter ratios of conical tubes were 0.882, 0.741, and 0.612. Experiments were carried out for conical tube heat exchanger of length 1 meter. The flow rate of water for inner tube considered 1LPM and for outer conical tube 1 LPM to 7 LPM. The heat transfer results of conical tubes were analysed and compared with the results of cylindrical tubes. Results reveal that the rate of heat transfer is inversely proportional to diameter ratio. A correlation was developed for a HTR of water flowing through outer conical tubes. Results revealed a rise of heat transfer rate up to 22%.
