Selection of Material for Improving Heat Transfer Rate for Fins using CFD
Fins are the extended surface jutting from a surface or body and which they are meant for increasing the heat transfer rate between the surfaces by increasing area for heat transfer. Heat flow in a system depends on three factors 1 area of the surface 2 temperature distinction and 3 the convective heat transfer coefficient. Rate of heat transfer can be magnified by enhancing any one of these factors. Out of these, the bottom surface area is restricted attributable to the design of the object temperature distinction depends on process and having process limitations. The sole alternative seems to be the convection heat transfer constant and this may not be magnified on the far side a certain worth. Therefore the potential choice is to extend the base surface area by the extended surfaces additionally called fins. Fins are therefore used whenever the obtainable surface area is found inadequate to transfer needed amount of heat with obtainable temperature gradient and heat transfer coefficient. In the case of fins the direction of heat transfer by convection is perpendicular to the direction of conduction heat flow. Present research work is devoted to the investigations of better fin material for an internal combustion engine. For this investigation help of simulation approach is being taken. Preceding in the direction of research, first of all a model of existing internal combustion engine was prepared. In next stage, along with existing material Al204 different materials, aluminnium alloy 7075, magnesium and beryllium, were also introduced in the model and thermal analysis was done on popular software ANSYS 15.0, under which three parameters were investigated, heat flux, directional heat flux and average temperature. Following are the details of conclusion drawn. 1. Beryllium shows itself most suitable material for the internal combustion fin application 2. Aluminum 7075 shows itself second most suitable material for the internal combustion fin application and 3. Aluminum 204 shows itself worst material for the internal combustion fin application.
