Abstract
Abstract The thermal attributes of porous fin due to radiation and natural convection have been carried out in the presence of nanofluid flow. The geometry of the fin taken for the analysis is rectangular profiled longitudinal fin. The temperature-dependent internal heat generation condition is also considered along with Darcy’s model. The two types of nanofluid containing titanium alloy ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mi mathvariant="italic">Ti</mml:mi> <mml:mn>6</mml:mn> <mml:mi mathvariant="italic">Al</mml:mi> <mml:mn>4</mml:mn> <mml:mi>V</mml:mi> </mml:math> ) and aluminium alloy ( AA 7075) immersed in water is considered for the investigation. The modelled nonlinear ordinary differential equation is numerically solved by the Runge–Kutta–Fehlberg technique. The impact of geometric parameter on the heat transfer analysis of the fin due to the flow of both nanofluids is plotted and consequences are physically interpreted. It is observed that the presence of the water-based titanium alloy better enhances the fin heat transfer rate.
