Design and Analysis of Heat Exchanger for Maximum Heat Transfer Rate

Heat exchanger as the name indicates it transfers heat from one fluid to another which are at different temperatures. Heat exchangers are devices built for efficient heat transfer from one fluid to another and are widely used in engineering processes. Some examples are intercoolers, pre-heaters, boilers and condensers in power plants. The heat transfer efficiency depends on both design of heat exchanger and property of working fluid. Some important design parameters such as the pitch ratio, tube length, and tube layer as well as baffle spacing. In this project, the heat transfer efficiency is improved by implementing the full baffle design and travel tube design and analyzing it through CFD flow simulation to find the approximate heat transfer rates. From the simulation results the optimum baffle design and travel tube design for maximum heat transfer rate is identified. Also this project deals with find the suitable fluid for maximum heat transfer rate.
