Design and Analysis of Helical Coil Heat Exchanger

Abstract

Heat exchangers has been widely used in power plants and industries for heating or cooling applications. Heat is transferred from one medium to another medium by using heat exchangers. Helical coil heat exchangers with two different shell configurations are designed. First shell configuration with a central core and second without a central core. Both the configurations has a copper helical coil. Designing of heat exchangers is done with counter flow arrangement by using CATIA V5 R2015. The performance of both the configurations are analysed and compared by using Fluid flow (Fluent) in ANSYS WORKBENCH 18.1 for CFD simulations. Further the helical tube materials Copper and Aluminium which are widely used in heat exchangers are also analysed in shell with core configuration and heat transfer rates are also compared using CFD (Fluent) analysis.
