Performance Analysis of a Fin in Steady State

Mindi Ramakrishna, N Chitti Babu, Boddu Manisha, G Durga Venkata Nagesh

A fin serves as an extended surface to enhance heat transfer from a larger mass to which it is attached. The project reports the designing of fin which involves the evolution of temperature profile in a fin which is approximately in the shape of Parabola. It includes the complete description of heat flow through fin by solving obtained non-linear equations using Shooting method. The results are analyzed and compared with conventional rectangular fin of same volume. Since, conduction and convection modes of heat transfer are essential in fin’s study, those two are taken into consideration and derived Efficiency and Effectiveness equations for the fin. The efficiency of the fin is found to be more than that of rectangular fin. In the considered system, the temperature distribution profile in one-dimensional steady state, as function of length of fin is drawn. It is attempted to model the system using “Mathematical Modeling” and by “Simulating” the system Using Matrix Laboratory (MATLAB).
