| description | Rotating nanofluid systems are widely utilized in energy systems, chemical processing, and biomedical devices due to their superior heat transfer characteristics. This study investigates the Darcy–Forchheimer flow of Reiner–Rivlin nanofluid over a rotating disk, incorporating the physical effects of solute transport and thermal energy flow. Motivated by the limitations in existing models that often neglect the simultaneous influence of nonlinear drag and non-Newtonian fluid behavior, the current analysis aims to fill this gap through an extended formulation. The governing partial differential equations (PDEs) are transformed into a system of coupled ordinary differential equations (ODEs) using similarity variables. These ODEs are then solved numerically using the BVP4c collocation method in MATLAB, over the interval [0,7], with boundary conditions applied at the disk surface and far field. The accuracy of the numerical results is validated through residual error analysis and comparison with benchmark studies. Detailed parametric studies are conducted for key variables, including the Reiner–Rivlin parameter (λ), porosity parameter (K), magnetic field parameter (M), and Forchheimer number (Fr). Results reveal that the combined effect of magnetic, porous, and nonlinear inertial resistance significantly suppresses the velocity field, while enhancing or diminishing the thermal and concentration profiles depending on the nanoparticle interaction. The tabulated results for Nusselt and Sherwood numbers, along with 12 % to 35 % variations across the studied parameter ranges, offer valuable intuitions for optimizing nanofluid-based rotating disk systems in industrial applications. |
