Computational Fluid Dynamics of Parallel Flow Heat Exchanger

Abstract

Heat exchangers are a class of Mechanical Components where heat transfer process takes place between cold and hot objects. As the machines need to be cooled heat is extracted. But this heat can be utilised in many ways in industries. So the best component available to extract heat from the exhaust gasses is by the use of Heat Exchangers. If the efficiency of heat exchanger is good maximum heat utilisation from waste gasses is achieved. The simplest heat exchanger available is parallel and counter flow indirect contact type heat exchange. But until now, there has been no attempt made in studying the heat pattern in a simple heat exchanger. So our project aims in analysis, of heat flow pattern of heat exchanger with the help of Fluent Software. We also proceed to determine the percentage error in experimental and analytical value obtained. In order to validate our results from the Fluent Analysis we have directly carried out the experiment on the parallel flow heat exchanger set up.
