Experimental Investigation of Heat Transfer in Double Pipe Heat Exchanger Using Cerium Oxide Nano fluid

Abstract

Heat exchanger is a very important device in every modern industry. In this research work, the thermal performance analysis of a pipe in pipe heat exchanger is performed by varying the composition of nanofluid used, which is a mixture of Cerium Oxide (CeO2) and water. An experimental analysis will be performed on pipe in pipe heat exchanger by varying volume concentration (2%, 3%, 4%) of nanoparticles in nanofluid at different flow rates (7, 8, 9 litres/min) of nanofluid flow. Experimental results such as heat transfer rates, overall heat transfer coefficient, Reynolds number, Nusselt number and heat exchanger effectiveness will be calculated to analyse the performance of heat exchanger. The objective of this research work is to check the use of Nano fluids to improve the heat exchanger’s performances and at what percentage of Nanoparticle-coolant mixture, the performance of pipe in pipe heat exchanger will obtain maximum heat exchange rate.
