Abstract
This article explores an incompressible hybrid nanofluid flow over an infinite impermeable rotating disk. The influence of a magnetic field has been added to better examine the fine point of nanoliquid flow. The main purpose of this work is to enhance our understanding of the exhaustion of energy in industrial and engineering fields. This study is mainly concerned with the von Kármán traditional flow of a rotating disk, involving carbon nanotubes (CNTs) and magnetic ferrite nanoparticles together with a carrier fluid such as water. The nonlinear system of differential equations is transformed to the dimensionless ordinary differential equation by using an appropriate similarity framework, which is further treated with the “homotopy analysis method” for the analytic solution. A mathematical calculation is provided to prove and illustrate why the hybrid nanofluids are advantageous as far as the heat transfer enhancement is concerned. Although the physical features highly rely on CNTs and iron oxide nanoparticles, it is concluded that the heat and mass transfer rate is greatly enhanced by the addition of CNTs and Fe3O4 nanofluids. By increasing the velocity of disk rotation, fluid temperature and velocity are significantly increased. The use of CNT + Fe3O4/H2O influences the performance of thermophysical characteristics of carrier fluids more compared to magnetic ferrite nanomaterials.
Highlights
The heat transfer with the fluid flow over the surface of a rotating disk has been receiving extraordinary attention from researchers due to its numerous applications in engineering and aeronautical sciences, such as thermal energy generating systems, gas turbine rotators, rotating machinery, geothermal industry, chemical processes, medical equipment, and computer storage. von Kármán1 reported the solution of Navier Stokes equations by selecting suitable transformation; for the first time, he introduced the fluid flow over a rotating frame

Summary
The heat transfer with the fluid flow over the surface of a rotating disk has been receiving extraordinary attention from researchers due to its numerous applications in engineering and aeronautical sciences, such as thermal energy generating systems, gas turbine rotators, rotating machinery, geothermal industry, chemical processes, medical equipment, and computer storage. von Kármán reported the solution of Navier Stokes equations by selecting suitable transformation; for the first time, he introduced the fluid flow over a rotating frame. Applying the electric field in the radial direction, Turkyilmazoglu studied the heat transfer phenomena in magnetohydrodynamic (MHD) fluid flow over a rotating disk. Shuaib et al. examined the frictional behavior of the viscous fluid flow over the surface of a flexible rotating disk with heat and mass transfer characteristics. Khan et al. studied the heat transfer of (single and multi-walled) CNT nanofluids over a plate surface. The enhancement of thermal characteristics of a carrier fluid, such as water, for industrial and engineering purposes and to explore the behavior of hybrid nanofluid flow under the magnetic effects over the surface of the rotating disk, is the main objective of the current study. The physical parameter effects are analyzed via tables and figures
