Experimental Analysis on Heat Exchanger by using Nano Fluids

The Nano fluids have emerged as a new generation of heat transfer fluids attracted the attention of researchers over the past few years. Recent investigation on Nano fluids such as suspensions are often called indicates that the suspended Nano particles markedly change the transport properties and heat transfer characteristic of the suspension. Nano fluids have great thermal physical properties such as thermal conductivity, thermal diffusivity, viscosity, heat transfer coefficient as compared to their base fluids .The key feature of Nano fluid is its superior thermal conductivity. The Nano fluids like Al2O3 + water, CuO + water, TiO + water are the very commonly used in thermal systems and heat exchangers. An experimental study of performance of AL2O3 Nano fluid in a heat exchanger was studied in the present work. Nano fluid is tested in a heat exchanger by varying the percentage of Nano particles mixed with water. Pure water is used in a heat exchanger and its performance was studied. AL2O3 Nano particles are mixed in water by 0.1 % & 0.2 % volume concentration and the performance was studied. The performance comparison has made between pure water and Nano fluids tested in heat exchanger. Nano fluids can be used to improve heat transfer and energy efficiency in many thermal control systems and heat exchangers.
