Computational Fluid Dynamics Analysis on Performance of Heat Transfer in Shell and Tube Heat Exchanger using Nano Fluids

Abstract

The simulations are carried out numerically to find out the effects like coefficient of heat transfer and pressure drop by using CFD. The heat transfer coefficient, pressure drop, overall heat transfer coefficient and performance factors are obtained. The CFD results of heat transfer coefficient, pressure drop and overall heat transfer coefficient are observed and compared with the experimental results. The transfer of heat to fluids and from fluids is vital between the basic operations in the industries. Heat exchangers enable efficient heat transfer between two mediums. In this way the temperature distribution can be changed when they are in direct or indirect contact. They can transfer heat between a liquid and a gas or two gases or they can work as a liquid to liquid heat exchanger. They are used in variety of industries. Based on requirements of the process, the type of fluid, viscosity, density, phase, temperature, pressure, chemical composition and size of the heat exchanger can be chosen. Greatest conceivable heat transfer coefficients can be accomplished by compelling both the fluids at the greatest conceivable mass flow rates and like providing hot fluid at higher temperature. Nano fluids are used for increasing thermal properties in heat transfer equipment like heat exchangers, radiators etc.
