Abstract: Thermal performance of heat transfer devices can be improved by heat transfer enhancement techniques In the present work, experimental investigations were conducted in a double pipe heat exchanger with hot and cold water as working fluids. The hot water is flowing in inner pipe and cold water in the annulus. Inserts when placed in the path of the flow of the liquid, create a high degree of turbulence, resulting increase in the heat transfer rate and the pressure drop. Nusselt number, heat transfer coefficient and overall heat transfer coefficient for different cold water mass flow rates is estimated keeping hot water flow rate is constant. Similar experiments were conducted for twisted tape having a twist ratio of 7.69. The Nusselt number and overall heat transfer coefficient with twisted tape are compared with those of base fluid. Then we will observe, overall heat transfer coefficient increasing with twisted tape insert. The experimental results indicates enhancement in heat transfer coefficient at 7.69 twist ratio when compared with plain tube at Reynolds number range of 2300 – 10,000. There would be a good agreement between the results obtained from the experimental and the analytical data.
Keywords: Enhancement techniques, heat exchanger, Nusselt number, twist ratio.
