Abstract

This study presents a numerical investigation of magnetohydrodynamic hybrid nanofluid flow and heat transfer between two rotating parallel plates in the presence of a porous medium, thermal radiation, viscous dissipation, and internal heat generation. The governing nonlinear partial differential equations are transformed into a coupled system of ordinary differential equations using appropriate similarity transformations and solved numerically using the MATLAB solver bvp4c. The effects of key controlling parameters, including the rotation parameter, magnetic parameter, permeability parameter, Eckert number, Prandtl number, radiation parameter, and heat generation parameter, on the velocity and temperature distributions are analysed. The results indicate that increasing rotation and magnetic field strength suppress the axial velocity, while rotation enhances the secondary flow due to Coriolis effects. The temperature distribution increases significantly with higher viscous dissipation, thermal radiation, magnetic field, and internal heat generation, whereas an increase in the Prandtl number reduces the thermal boundary layer thickness. These findings provide useful insights into controlling flow behavior and thermal performance in rotating magnetohydrodynamic hybrid nanofluid systems.
