Darcy-Forchheimer flow of Ag–ZnO–CoFe₂O₄/H₂O Casson ternary hybrid nanofluid induced by a rotatory disk with EMHD

Abstract

This study comprehensively inspects the steady, three-dimensional electromagnetohydrodynamics Darcy-Forchheimer slip flow upon a Casson ternary hybrid nanofluid through a porous rotatory disk. The study plunges into the repercussions of key factors namely thermophoresis, chemical reaction, viscous dissipation, Brownian movement, thermal radiation, and activation energy attributes of the ternary hybrid nanofluid. The current endeavour is inspired by the flourishing requirement in several energy-related and industrial applications. A mathematical configuration is formed to express the fluid flow system and heat and nanoparticle mass transpiration processes. Then partial differential equations administrating our mathematical model, are reformed into ordinary differential equations with the assistance of specific similarity conversions and eventually interpreted numerically using the noteworthy bvp4c scheme. The consequences of discrete flow factors upon temperature, concentration, and velocity profiles and Nusselt number, skin friction’s coefficient, and Sherwood number are investigated. The achieved outcomes disclose the electric parameter aids in upgrading the tangential velocity and temperature profiles. The outcomes reveal that for Casson ternary hybrid nanofluid, the heat and mass transpiration rates elevate by 19.23% and 51.28%, respectively, compared to Casson nanofluid whereas skin friction coefficient is retrogressed by approximately 8.96% for Casson ternary hybrid nanofluid compared to ternary hybrid nanofluid.
