Abstract
- A heat exchanger is a device used to transfer thermal energy between two or more fluids, at different temperatures in thermal contact. Enhanced heat transfer is a heat transfer that has been improved. The study of improved heat transfer performance is referred to as the heat transfer enhancement, augmentation or intensification. Heat exchangers have special and practical applications in the feed water cooler in the process industries, power plants, chemical plants, refineries, process applications as well as refrigeration and air conditioning industry. Experimental investigation has been carried out to study the effect of overall heat transfer coefficient in twisted tube heat exchanger. The main aim of this experimentation is to determine the overall heat transfer coefficient and friction factor of twisted tubes in multipass arrangement, with water as a working fluid. The experimental model was validated with the computational model.
