Heat transfer analysis of a fully wetted moving radial porous fin on an inclined surface in presence of convection and radiation

The present paper focuses on the thermal behaviour of a moving radial porous fin mounted on an inclined surface and subjected to a convective-radiative environment. This study bridges the gap between theoretical models and practical applications, enabling engineers to design systems with higher reliability and performance. It has been assumed that the fin structure is porous and completely wet in nature. The solid fluid interactions have been simulated using the Darcy model. The resulting governing equation has been nondimensionalised by using suitable non-dimensional quantities and then solved by using Runge-Kutta Fehlberg 4-5th order method. The impact of pertinent parameters such as angle of inclination, fully wet nature, convective, radiative, thermal conductivity and other relevant aspects on the thermal profile of the fin have been examined and graphically illustrated. The obtained outcome has been compared with the homotopy analysis method as well as finite element method and the results are found to be in good agreement. It is inferred that the fin cooling increases with increasing values of the convective, radiative, angle of inclination and wet porous parameters. The current work has significance for the fin design and serves as a validation tool for further investigations. The present study has wide number of applications in the field of thermal management in electronics, solar collectors, aerospace, gas turbines, nuclear power plants, air Conditioners, refrigeration and so on.
