“…It has been extensively functional in atmospheric heat conditioning, automotive, heat transfer equipment, etc. The main objectives of these investigations are dropping the dimensional/geometrical perspectives and material price of fin-based system (3)(4)(5)(6)(7)(8) . The enhancement of heat dissipation capabilities in extended surfaces or fins have been given preferences in research and development that has guided to utilization on the use of porous fins.…”

Background/ Objectives: Porous-permeable structured fins are the principal operational mechanism for enhancing the percentage of heat evolved and dissipated because of their many thermo physical characteristics. Study of thermal gradients on the basis of convective loads in porous fins is important in many engineering fields. Methods: In the present fractional investigation, well-established optimal homotopy asymptotic method (OHAM) has been applied on thermal system expressed in nonlinear fractional order of ordinary differential equations for Darcy's approach for porous-structured fin. Here parameters related to porosity, permeability and convection have been deliberated. In order to study the thermal solicitations, the thermal analysis with insulated tip of copper based alloy is studied. Findings: It is found that porosity of system is influencing more than other factors. Novelty: This study demonstrates the efficiency of OHAM as well.

“…In the last few years, a number of good works on the metaheuristic optimization of fins of different profiles and under different cases has been done. Das 28 used a hybrid differential evolution (DE)-non-linear programming optimization algorithm to predict three unknown parameters. This inverse analysis was done to satisfy a known temperature distribution by selecting a number of possible combinations of parameters.…”

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.

“…Consequently, research on the phenomena of heat transfer using porous fin has become one emerging research area for engineers and designers. This is because, for equal weight, porous fin has been established to show better performance than solid fins when operating under the same thermal conditions with the same geometrical configurations [2,3].…”

Numerical investigation of inclination effect on the thermal performance of a porous fin heat sink is presented. The developed thermal model is solved using pseudo-spectral collocation method (PSCM). Parametric studies are carried out using PSCM, and the thermal characterization of heat sink with the inclined porous fin of rectangular geometry is presented. Results show that heat sink of inclined porous fin exhibits higher thermal performance than heat sink of vertical porous fin operating under the same thermal conditions with the same geometrical configurations. Performance of inclined or tilted fin increases with decrease in length-thickness aspect ratio. However, increase in the internal heat generation parameter decreases the fin temperature gradient which invariably decreases the heat transfer performance of the fin. Furthermore, the results of the pseudo-spectral collocation method are compared with the results of Runge-Kutta method. Excellent agreement is established between the results of the non-convectional numerical method and the results of Runge-Kutta, which validates the accuracy of the method for analysis of nonlinear heat transfer problems. The results presented in this paper, hopefully, serves as motivation for the design and optimization of thermally-enhanced heatsinks.
