“…By applying the energy balance equation to a differential volume of fin by neglecting the heat flow in transverse direction and taking in to account only the longitudinal heat transfer in the porous fin with internal heat generation, we get 11,12,51 where mass flow rate of the fluid passing through fin pores is …”

“…Heat flow through the tip is neglected in order to reduce the added complexities in the equation due to the tip heat flow. But in a study conducted in the year 2018 by Deshamukhya et al., 51 it was seen that for a finite length fin, tip does play an important role and leads to better heat transfer rate and thus its role in enhancing the rate of heat transfer can be ignored only when the length of the fin is appreciably high and not otherwise. This study was a realistic approach to show the role played by the fin tip in transferring heat in real life scenarios and needless to mention here that an appreciable heat transfer rate through convective fin tip has been recorded.…”

In this novel optimization analysis, a rectangular porous fin subjected to convective tip conditions along with insulated end condition is studied. The aim is to optimize the important variables responsible for transferring heat from fin with insulated as well as convective tip to the surrounding in order to get a higher rate of heat transfer from the fin surface. Temperature-dependent solid and fluid thermal conductivities as well as variable internal heat generation is considered. To obtain heat dissipation rate through porous fin, the nonlinear governing equation is first solved analytically using Adomian decomposition method. Then the heat transfer rate, i.e., objective function of this problem is optimized with three powerful metaheuristic techniques, namely firefly algorithm, particle swarm optimization and gravitational search algorithm. A comparative analysis has revealed that fins with convective end show significantly higher heat transfer rate compared to their insulated end counterparts. Particle swarm optimization showed marginally higher heat transfer values compared to firefly algorithm but firefly algorithm took less computational effort to reach the optimum value.

“…In the subsequent publication, Deshamukhya et al. 11 continued this work where they studied the efficiency and optimization of rectangular porous fins considering both insulated and convective tip conditions. The authors considered temperature-dependent thermal energy generation and temperature-dependent thermal conductivities of fin material and fluid passing through fin pores for the analysis.…”

The current study deals with the optimization of significant parameters of aluminium and copper rectangular porous fins using firefly algorithm with reflective boundary condition. The study has been done considering convective heat transfer, in the first case, as well as combined convective and radiative modes of heat transfer, in the second case. To solve the non-linear governing equation, a semi analytical technique, differential transformation method is adopted. The results obtained by differential transformation method are validated by the numerical solution obtained by the finite difference method. The performance of firefly algorithm is evaluated by comparing with the results obtained by particle swarm optimization where it is seen that for the current set of equations, firefly algorithm took lesser number of iterations and computational time to converge than particle swarm optimization for all the cases. The analysis has been done for three different fin volumes and the effect of important variables which directly influence the heat transfer rate through porous fins has been discussed.
