Numerical Simulation of Fins Mounted On Inner Tube of Single Tube Fire Water Heater

HEAT TRANSFER

The rate of heat transfer to water around a pipe can be greatly enhanced by the use of extended fins. The main objective in improving the performance of thermal system is to enhance heat transfer. To increase thermal performance of water heating boiler, it is necessary & effective to employ extended surface, referred to as fins, on the central pipe, to compensate for the low heat transfer coefficient. The prototype finned tube consists of equi spaced fins mounted on the outer surface of tube, in order to locally augment heat transfer between the fin base area & the surrounding fluid. Because heat conducted through fins is very efficient for metals, it results in high fin surface temperature and an increase of total active area.
