Heat and Mass Transport in Magnetized CNT-Infused Hybrid Ellis Nanofluid Flow Over a Porous Stretching Surface

Abstract

The overarching aim of this study is to investigate the enhancement of thermal energy and mass transfer in the flow of Ellis hybrid nanofluid under a magnetic field across a porous stretching surface. This advanced hybrid nanofluid is formulated by dispersing single-walled and multiwalled carbon nanotubes (CNTs) within a non-Newtonian Ellis fluid. The research meticulously analyzes the complex interactions of velocity, heat, and mass transport influenced by thermal radiation, nonuniform heat sources/sinks, Joule heating, and Arrhenius activation energy. The governing nonlinear partial differential equations are skillfully transformed into ordinary differential equations through elegant similarity transformations, and the resulting dimensionless equations are solved semianalytically using the sophisticated Homotopy Analysis Method. The key findings indicate that viscous dissipation and heat generation significantly elevate energy profiles, while Arrhenius activation energy profoundly boosts mass transfer rates. Additionally, the integration of CNTs into the Ellis fluid enhances both velocity and energy fields, demonstrating remarkable improvements in heat and mass transfer efficiency. The Ellis hybrid nanofluid holds immense potential for applications in engineering and industrial processes, including polymer extrusion, food processing, and pharmaceutical manufacturing, where precise control of shear-thinning fluid behavior is vital for optimizing performance.
