Magnetized transport of chemically reactive viscoplastic nanomaterials with dual diffusion driven by a rotating disk

Abstract The ability to maintain continuous thermal propagation is essential in various industrial and thermal systems, as it contributes significantly to improve the efficiency of thermal production engines and equipment. Consequently, incorporating magnetized nanoparticles into a non-Newtonian fluid that carries heat offers an exciting opportunity for enhancing thermal power energy. The present study highlights diffusion-thermo, Robin conditions, and thermo-diffusion impacts in Casson nanofluid configured by rotating vertical disk. Flow formulation includes magnetic field and mixed convection effects. Thermal features like radiation and heat generation are considered for modeling energy expression. Species concentration is examined by considering chemical reaction. The governing partial differential equations have been made dimensionless through the use of similarity transformations, which have allowed them to be reformulated as ordinary differential equations. The bvp4c method is deployed for numerical simulations. The pertinent variables have been visually depicted through graphs, along with calculations of other engineering quantities like the mass transport rate, skin friction coefficients, and heat transport rate. The outcomes display that the radial fluid velocity of Casson nanofluid declines with an upsurge in the values of the magnetic variable, Casson fluid variable, buoyancy ratio variable, and mixed convection variable.
