Nowadays due to increasing temperature conditions the application of different heat exchangers are to be developed to increase its performance. These heat exchangers are used in applications such as refrigeration, air conditioning systems, power plants, chemical processing systems, food processing units, automobile radiators and waste heat recovery units. In this study heat transfer analysis was done on the W Pipe heat exchanger type of coil. This analysis was performed for enhancement of heat transfer in a pipe using Nano fluids as coolants. Nano-particles such as Al2O3 and SiO2 are used along with base fluid water. Different concentrations such as 0.5%, 1%, 1.5% & 2% of nanoparticles are mixed with water. The study is done virtually by using ANSYS 15.0 fluent platform. Properties of Nano fluids are determined by using the formulations followed by base papers. The results such as pressure, velocity and heat transfer coefficient are determined. Results proved that Al2O3 has high heat transfer rate and also it is studied that SiO2 with water has high-pressure increase
