Abstract
Heat exchanger is used for heat transfer from one hot fluid to cold fluid. The performance of heat exchanger is analysed by of the heat transfer rate and heat transfer coefficient. The main objective of this research work is increased the performance of the heat exchanger by using Nano fluid. CFD analysis is performed for the estimation of heat transfer rate and heat transfer coefficient of Nano-fluid flow in a double pipe U-bend heat exchanger. The prototype of U-bend heat exchanger was developed using ANSYS 14.0 workbench. In this study Aluminium oxide (Al2O3,), Copper oxide (CuO), and Ethylene Glycol are used as a Nano fluids The volume fraction of Nano fluids are 0.2%, 0.3% and 0.4% were used in this analysis. The mass flow rate of hot fluid kept constant and the mass flow rate of Nano-fluids are varies from 0.154 kgsec. The temperatures of Nano-fluids flow in a heat exchanger are kept at 343 K. The results revealed that as volume fraction are increased the heat transfer rate and heat transfer coefficient are increased, and Velocity and pressure are decreased. Based on the numerical results, the highest value of heat transfer coefficient is obtain from Al2O3 Nano-fluids with 0.02% volume fraction and highest heat transfer rate is CuO Nano fluid with 0.03% volume.
