“…In an investigation by Alireza et al. 83 on porous fins inside an inclined enclosure, the optimum length was found to decrease with Rayleigh number. An interesting finding from the vast literature database of two decades related to porous fins have showed that apart from the research carried out by Deshamukhya et al., 84 the fin tip has always been ignored or considered to be insulated.…”

The high-end devices, sophisticated gadgets, smart home appliances, superfast vehicles and aero engines of twenty-first century demand better heat removal for efficient functioning. Thus, with an aim to facilitate higher heat transfer from mechanical and electronic equipment, extensive research throughout the world has been going at a steady pace. One such achievement in the field of heat transfer is the introduction of the porous fins. This paper aims to discuss the various important aspects of porous fins along with the noteworthy research and developments in this field over the last decade. The review starts with a brief idea of heat transfer mechanism through porous media followed by some discussion on the thermal analysis of porous fins. Usually, the complicated nonlinear energy equations of porous fins require analytical techniques along with numerical analysis to solve the same. A good number of relevant research works have been cited to understand the optimum shaping and derivation of governing differential equations. Finally, a strengths, weakness, opportunities and threats analysis has been done to analyze the various aspects of using a porous fin.

The performance and thermal properties of convective–radiative rectangular and moving exponential porous fins with variable thermal conductivity together with internal heat generation are investigated. The second law of thermodynamics is used to investigate entropy generation in the proposed fins. The model is numerically solved using shooting technique. It is observed that the entropy generation depends on porosity parameter, temperature ratio, temperature distribution, thermal conductivity and fins structure. It is noted that entropy generation for a decay exponential fin is higher than that of a rectangular fin which is greater than that of a growing exponential fin. Moreover, entropy generation decreases as thermal conductivity increases. The results also reveal that entropy generation is maximum at the fin’s base and the average entropy production depends on porosity parameters and temperature ratio. It is further reveal that the temperature ratio has a smaller amount of influence on entropy as compared to porosity parameter. It is concluded that when the temperature ratio is increases from 1.1 to 1.9, the entropy generation number is also increase by $$30\%$$ 30 % approximately. However, increasing porosity from 1 to 80 gives 14-fold increase in average entropy generation.

“…They found an excellent substitute for reducing cylinders' angular speed by using a porous material of high permeability and eventually decreasing the energy needed. Keyhani‐Asl et al 27 analyzed the thermal effect of porous fins on the inclined rectangular cavity. They have shown that applying such fins boosts the cavity's natural convection by about 40%.…”
