COMPARATIVE ANALYSIS OF SHELL AND TUBE TYPE HEAT EXCHANGER WITH EFFECT OF HELICAL BAFFLES AND NANO FLUID: A REVIEW

In shell and tube type heat exchanger, the thermal performance and pressure drop are dependent on the type of fluid flow and type of baffles used in it.Inorder to improve the efficacy of heat exchangers, Nano fluidsare recently employed as coolants in them.Regarding unique characteristics of Nano fluids, research studies in this area have witnessed a remarkablegrowth.This paper presents the simulations carried out on different baffle i.e. helical baffles and different type of fluid i.e. Nano fluid and water. This shows the effect of baffles on heattransfer of fluid in shell and tube heat exchanger. Single segmental baffles show the formation of dead zones where heat transfer cannot do properly. Double segmental baffles reduce the vibrational damage to system as compared to single segmental baffles.The use of helical baffles can decrease in pressure drop by the elimination of dead zones. The less dead zones result in high heat transfer. The helical baffles can create the turbulence flow, which increase heat transfer rate, which increases the overallefficiency of the system.In this paper we will comparatively study of shell and tube type heat exchanger with Nano fluid and water on different mass flow rates
