The study of coupled reaction transport in Casson rheology bridges the gap between idealized Newtonian models and practical non-Newtonian fluids, as chemically reacting nanoparticles alter the concentration and thermal behavior of the base fluid. This complexity intensifies when nanoparticles are introduced into conventional refrigerants. This work presents a unified investigation of radiative and viscous dissipative magnetohydrodynamic flow of a chemically reacting Casson nanofluid over an inclined slippery stretching surface embedded in a non-Darcy porous medium. The simultaneous consideration of Casson rheology, nanoparticle-enhanced heat transfer, magnetic control, surface slip, chemical... More >
