Modelling and Analysis of Straight Tube and Helical Tube Heat Exchanger using Computational Fluid Dynamics

Heat exchangers find extensive use in industrial applications such as automotive systems, power generation, nuclear industry, process plants, heat recovery systems, refrigeration systems, food industry, etc. A heat exchanger is a device where two fluids streams come into thermal contact in order to transfer the heat from hot fluid to cold fluid stream. It has been widely reported in literature that heat transfer rates in helical coils are higher as compared to those in straight tubes. Due to the compact structure and high heat transfer coefficient, helical coil are a preferred means of heat transfer which is finding application in the industry. In this investigation the aim is to identify the effects of variation of Helical Pitch, the Helical diameter and the effect of orientation on the heat transfer rate and efficiency for helical heat exchangers Citation: Santhosh K M, MACE, Kothamangalam; Dr. Benny Paul ,MACE, Kothamangalam; Professor George Mathew ,MACE, Kothamangalam; Professor Sabu Kurian ,MACE, Kothamangalam; Dr. Cibu K Varghese ,MACE, Kothamangalam.
