Performance of Different Types of Fins in Porous and Non-Porous Media
Heat is a form of energy that can be transferred from one system to another, as a result of temperature different. The transfer of energy as heat is always from higher temperature medium to the lower temperature. The science that deals with determinations of rates of energy transfer is HEAT TRANSFER. Heat transfer by convection between a surface and the fluid surrounding can be increase by attaching thin strips of metals to the surface called Ã¢â‚¬Å“FINSÃ¢â‚¬Â. These are the extended surface used to increase the surface area. Fins are most commonly used in heat exchanging devices such as radiators in cars and heat exchangers in power plants. They are also used in newer technology such as hydrogen fuel cells. Nature has also taken advantage of the phenomena of fins. The ears of jackrabbits and Fennec Foxes act as fins to release heat from the blood that flows through them. In our project different cross-section of fins are used. For these fins the performance i.e. efficiency and effectiveness are calculated with both porous and non-porous media.
