CFD Analysis of Natural Convective Heat Transfer in Helical Coiled Heat Exchanger
Keywords:Helical coil, Natural convection, Heat exchanger
This paper focuses on the CFD analysis of flow of fluid through a helical coil heat exchanger. Also, on the enhancement in convective heat transfer in between the fluid and the surrounding surface in these helical coils which has been a major topic of study as reported by many researchers. As helical coil has compact size and higher heat transfer coefficient, they are widely used in industrial applications such as power generation, nuclear industry, process plant, refrigeration, food industry, etc. In this study, an attempt has been made to study the stagnant hot fluid inner chamber as a bath and outer cold fluid flow, which are separated by copper surface in a helical coil heat exchanger. The temperature contours, velocity vectors, total pressure contours, total heat dissipation rate from the wall of the tube were calculated and plotted using ANSYS 18.2. Copper was used as the base metal pipe and the fluid was taken as cold water for inner flow and soap solution and CMC as a bath.
