Thermal investigation of fully wet longitudinal porous fin of functionally graded material

Abstract

Purpose The purpose of this study is to conduct a numerical computation to analyse the thermal attribute and heat transfer phenomenon of a fully wetted porous fin of a longitudinal profile. The fin considered is that of a functionally graded material (FGM). Based on the spatial dependency of thermal conductivity, three cases such as linear, quadratic and exponential FGMs are analysed. Design/methodology/approach The governing equations are nondimensionalised and solved by applying Runge-Kutta-Fehlberg fourth-fifth order technique. Findings The parametric investigation is executed to access the significance of the pertinent parameters on the thermal feature of the fin and heat transmit rate. The outcomes are portrayed in a graphical form. Originality/value No such study has yet been published in the literature.
