HEAT TRANSFER RATE ENHANCEMENT BY PERFORATED FINS: A REVIEW
Keywords:
Natural convection,perforated finAbstract
Heat dissipation is one of the main problems which we come across while dealing with high load and high speed
machines. Because of the work they perform, some amount of heat is generated inside the machine. This heat has to be
transferred outside the system to obtained efficient output. If it is not done, then this heat may cause damage to machine
parts. To do this, fins are used. Main purpose of fins is to increase surface area of machine so that heat can be transmitted in
atmosphere. In this project, we are trying to increase surface area of fins by providing perforations to it. these perforations
may be of any shape and size. Our aim is to find those shapes and size which will increase the efficiency of fin.
