Comparative Study on Thermal Analysis of Extended Surface Using ANSYS Simulation

Abstract

Extended surface are heat exchangers generally made on the external circumference of an object that are mainly used to enhance the heat transfer rates through a combination of conduction and convection mode of heat transfer. In general, extended surface are made up of the materials whose thermal conductivity is maximum to facilitate more amount of heat transfer to or from the environment and also available in different profiles with respect to the applications of the components. Among the different types, the most commonly used are longitudinal type of fins, i.e. when the direction of flow of the fluid is parallel to the axis. In this research work, an attempt has been made to compare three different profiles like rectangular, trapezoidal, and concave parabolic fins using ANSYS simulation software. Thermal analysis using ANSYS simulation is one of the important techniques to analysis the efficiency of the fin with different profiles. The model of the fin profiles is made by fusion 360 and the comparative study on thermal analysis is carried by employing ANSYS simulation. From this research output, the trapezoidal of the extended surface has better results than the conventional rectangular as well as profile concave parabolic in various thermal properties, and hence it is great replacement of in near future.
