Abstract :

In present study, in order to increase of heat transfer in a horizontal circular tube heat exchanger by means of Snail Entrance with air as the working fluid. In the experimental set up, cold air in ambient condition was passed through the inner pipe while hot water was flowing through outer tube. The Reynolds no of air varies from 10000 to 60000. The results are compared with the plain tube where no Snail Entrance was used. The work includes the determination of friction factor and heat transfer coefficient for snail entrance in both counter and parallel flow. Snail entrance was observed that the heat transfer coefficient could vary from 90 to 110% the smooth tube value but the corresponding friction factor increases by 1 to 1.3 times the smooth tube values. It was also observed that with an increase in Reynolds number (Re), the heat transfer coefficient increases where as the friction factor decreases.
