Thermal transport of magnetized hybrid nanofluid swirling over a disk surface with Hall current and thermal radiation effects

Abstract

The current research focuses on the impact of Hall current on the flow of hybrid nanofluids over an unsteady, radially stretching, and rotating slippery disk surface. Additionally, the noteworthy characteristics of the Lorentz force resulting from the collaboration of the magnetic field with the motion of hybrid nanofluids are investigated. The convective condition, heat source/sink, and thermal radiation are used to study the heat transfer process. In the present physical model, which is made up of aluminium oxide (Al2O3) and copper oxide (CuO) with water, a novel class of nanofluids known as the hybrid nanofluid is being used. The system of partial differential equations from the current model is converted into ordinary differential equations using similarity transformations and then solved using the bvp4c scheme in MATLAB. The statistics show that a hybrid nanofluid transfers heat at a rate that is significantly higher than a nanofluid. Furthermore, it is noted that the Hall current effect increases radial and azimuthal flows while lowering the fluid temperature. By changing the radiation and Eckert numbers, energy transport is improved.
