Rotating Casson nanofluid flow with generalized heat and mass transport

A theoretical investigation is conducted to explore the three-dimensional Casson nanofluid flow affected by the double diffusion effects in Casson nanofluid over a stretching sheet, considering viscous dissipation, thermal radiation, an inclined magnetic field, a porous medium, a chemical reaction, and heat generation/absorption. The study addresses a research gap by incorporating the Cattaneo-Christov double diffusion model into the rotating Casson nanofluid framework, which has not been previously considered in such a three-dimensional flow. The inclusion of radiative heat and inclined magnetic field effects further enhances the novelty of the current work. The governing nonlinear partial differential equations are transformed into ordinary differential equations using the similarity transformations and solved numerically via the shooting method. Key transport mechanisms such as thermophoresis, Brownian motion, and thermal and mass relaxation effects are analyzed. The results indicate that a ۴۰% increase in the Casson parameter leads to a reduction in the heat transfer rate by up to ۲۳%. An increased rotation and magnetic field strength also contribute to the reduced velocity and thermal profiles. This research provides a deeper understanding of non-Fourier heat and mass transport in non-Newtonian fluids. The findings are applicable to cooling technologies, polymer processing, and enhanced heat transfer systems involving electrically conducting fluids.
