Abstract:
A variety of industries use coiled tube heat exchangers for the heating and cooling of liquids and gases. Helically and spirally coiled tubes are utilized for single-phase, evaporating, and condensing flows. The aim of this research was to study the heat transfer characteristics of a helical cone coil heat exchanger and to obtain heat transfer rate, heat transfer coefficients and effectiveness. It was also intended to compare these results with the available results of helical coil heat exchangers. To accomplish this experimental set up of helical cone coil heat exchanger was developed. Helical cone coil was manufactured for slant edge angle 70. In experimentation, hot water is allowed to flow through the coil and cold water was flowing through the shell respectively. Variation of mass flow rate of coil fluid and shell fluid was considered in the range of 0.02 to 0.10 kg/s respectively. Cold water exit temperature, rate of heat transfer, heat transfer coefficients, effectiveness and modified effectiveness were obtained for variation of mass flow rate of shell fluid and coil fluid. Further these results were compared with results of researchers. It is found out that as hot water mass flow rate increases cold water exit temperature and rate of heat transfer increases. When mass flow rate of cold water increases from 0.05 kg/s to 0.1 kg/s, effectiveness is found to decrease for increase in hot water mass flow rate. Also modified effectiveness is found to decrease as ratio of mass flow rates of both fluids increases. Tube side heat transfer coefficients and Nusselt numbers are found to increase when hot water mass flow rate increases. Results obtained in this study are in agreement with results of researchers.

Keywords: helical cone coil heat exchanger, inside heat transfer coefficients, effectiveness, logarithmic mean temperature difference
