TRANSIENT STATE ANALYSIS OF CYLINDRICAL FIN USING SIMULATION METHOD AND COMPARE DIFFERENT FIN MATERIAL

Fins are extensively used in heat exchanging devices in automobiles radiators, industrial sectors, power plants, newer technology like fuel cells. Generally, the material used for the application of fins is aluminium alloys. In this present work Thermal behaviour of cylindrical fin is numerically investigated using Ansys APDL Software for different materials like Brass, Aluminium and Copper. Transient state analysis is carried out for the cylindrical fin under the convection and a specified base temperature condition. The length, base thickness, and end thickness of the fin is specified.. Transient solutions had been derived earlier by various researchers. Thermal conductivity of the fin material is specified. A constant temperature condition is applied at the base of the fin convective boundary conditions applied at the tip of the fin. Comparative study is being done among the fin material here used to find out the best material under the conditions. Base heat transfer rate, time to reach steady state, temperature distribution at different times, steady state temperature distribution is investigate
