Performance Analysis of Porous Fins for Enhanced Heat Transfer

Abstract Abstract: The present study introduced a novel methodology for enhancing heat transfer performance from a specified surface through the application of porous fins. The thermal efficiency of porous fins was systematically evaluated and subsequently compared with that of conventional solid fins. The analysis demonstrated that the incorporation of porous fins with porosity ε (epsilon) significantly improved thermal efficiency when compared to equivalent solid fins. Furthermore, the adoption of porous fins contributed to a reduction in fin material consumption by approximately 100ɛ (100 epsilon) percent, indicating both thermal and material optimization.
In addition, the study investigated the influence of various design and operational parameters on the thermal efficiency of porous fins. These parameters included the Rayleigh number (Ra), Darcy number (Da), and thermal conductivity ratio. The findings revealed that enhanced thermal efficiency could be achieved at elevated Rayleigh numbers, particularly under conditions of larger Darcy numbers. Moreover, the results indicated the existence of a critical thermal conductivity ratio, beyond which no further improvement in fin efficiency was observed. These outcomes highlighted the significance of porous fin structures as an effective approach for heat transfer enhancement and material savings in thermal engineering applications.
