Design and Thermal Analysis of an Extended Surface with Various Geometry by using Finite Element Method

A fin is a surface that extends from an object to increase the rate of heat transfer to or from the environment by increasing convection. Increasing the temperature gradient between the object and the environment, increasing the convection heat transfer Coefficient or increasing the surface area of the object increases the heat transfer. Extensions on the finned surfaces is used to increases the surface area of the fin in contact with the fluid flowing around it. So, as the surface area increase the more fluid contact to increase the rate of heat transfers from the base surface as compare to fin without the extensions provided to it. The heat transfer performance of fin with same geometry having various extensions and without extensions will compared and also with holes on extended surface and without holes on extended surface also compared. Fin with various extensions design with the help of software AutoCAD software and Analysis of fin performance done through the software Autodesk® Simulation and meshing using hyper meshing software and ANSYS.
