Abstract

Heat exchangers are important devices used in power plants and chemical industries. In order to obtain larger heat transfer rate per unit volume helically coiled heat exchangers are preferred over straight tubular heat exchangers. This paper deals with the study of effect of different design parameters like tube diameter, pitch circle diameter and pitch of the coil on heat transfer through helical heat exchanger. A helical coiled heat exchanger was simulated for constant wall temperature boundary conditions. It was observed that nusselt number, heat transfer coefficients and pressure drops were significantly influenced by changing the tube diameter and pitch circle diameter of the coil whereas coil pitch influences the least on the heat transfer characteristics.
