FEM integrated simulation of radiative MHD nanofluid flow via slanted stretching cylinder: unraveling coupled thermo-magnetic and geometric effects

Abstract

Nanofluid flow over a slanted stretching cylinder has impactful applications in heat exchangers, fiber and polymer processing, solar collectors and biomedical devices, as the flow of heat and mass can be greatly improved by the inclined geometry. In light of the listed substantial applications, this research investigates the impacts of curvature, viscous heating, angle-inclination, chemical interactions and Soret and Dufour facets on the radiative thermal propagative MHD nanofluid migration in the prevalence of convective heat and mass transfer via the slanted cylindrical structure ingrained in porous medium. The two types of nanoparticles Ag and Al2O3 are mixed with base fluid water to synthesize two different nanofluids. With the aid of MATLAB software, finite element method (FEM) was engaged to simplify the final ODEs aiming to perform the model’s objectives. The ultimate outcomes revealed that thermal and velocity fields of both fluids noticeably increased by the viscous heating, thermal Biot number and heat radiation. The curvature and thermos-diffusion impacts incited to amplify all three flow fields. The flow velocity of both fluids substantially depreciated with magnetic field and inclination angle. The greater thermal source and diffusion-thermo instigated to rise thermal fields The concentration field of both fluids condensed by the solute Biot number and chemical reactive parameters. The friction-factor decreased pointedly by the nanoparticle concentration, angle inclination, Hartman number, curvature and viscous dissipation. Increased magnetic field, curvature and angle inclination of the surface caused to rise the Nusselt number. The Sherwood number appreciably raised with the chemical reaction, curvature and solutal Biot number.
