Keywords:

Double pipe heat exchanger, Heat transfer enhancement, helical fin and rectangular fin and techniques comparison.

Abstract

Now a days, heat transfer enhancement in heat exchangers is most important. Heat transfer enhancement is the process of improving the performance of a heat transfer system. It generally means increasing the heat transfer coefficient. The various heat transfer enhancement techniques are available such as finned surfaces integral roughness, insert devices and using nano fluids. In this paper, comparison of two heat transfer techniques are insertion of rectangular fins and helical fin in double pipe heat exchanger by using CFD analysis. Here, 8 rectangular fins and 20 mm pitch length in 750 mm length double pipe heat exchanger used and both fin thickness is 2 mm. The performance of heat exchanger of temperature distribution and pressure drops are analyzed, the best heat exchanger is displayed and the reasons are discussed.
