A hybrid approach to study the influence of Hall current in radiative nanofluid flow over a rotating disk

The present work is focused on the impact of Hall current on hybrid nanofluids flow over an unsteady rotating as well as radially stretching disk. Further, the significant features of Lorentz force due to the magnetic field interaction with hybrid nanofluids motion are explored. The process of heat transfer is inspected with thermal radiations and heat dissipation. An innovative group of nanofluid model known as the hybrid nanofluid is being utilized in the current physical model, which are composed of copper (Cu) and aluminum oxide (Al2O3) with water. The system of PDEs of the present model is transformed into ODEs by employing similarity transformations and then solved with bvp4c scheme in MATLAB in the light of parametric study; it is concluded from the tabular data that rate of heat transfer is significantly high in the case of hybrid nanofluid as compared to nanofluid. Further, it is noted that Hall current effects enhance the radial velocity, while decreasing the cross-radial factor and temperature of the fluid. The rotation of disk causes to enhance the radial, axial velocities and temperature profile by increasing the rotation parameter. Temperature profile enhances by varying Eckert number and radiation parameter. It is further noted that the velocity of fluid decreases by enhancing magnetic field parameter, while the temperature increases.
