Electrically conducting water-based hybrid nanofluid flow between two stretchable rotating disks: A numerical analysis

Abstract

This article presents a numerical analysis of the water-based hybrid nanofluid comprehending CuO and Fe₃O₄ nanoparticles between two rotating disks. The bottom and top disks each revolve around their respective axes of rotation. The two disks are positioned apart from one another. Along with Brownian motion and thermophoresis, it is intended that the flow will be electrically conducting, thermally radiative, and chemically reactive. The heat and mass transportation are also given attention in this study since they are crucial for industry, engineering, and everyday life which include hydraulic engines, electric motors, and generators. Using the bvp4c MATLAB function, the numerical solution of the modeled problem is ascertained. The results of the current numerical solution are compared with results from published research, confirming the accuracy of our model. The results of the present analysis are presented through figures and tables. Outcomes of this analysis show that stretching factor of the lower disk upsurges the axial velocity while the radial velocity exhibits dual behavior due to the stretching factor of the lower disk. Also, the stretching factor of the upper disk reduces the axial velocity while the radial velocity exhibits dual behavior due to the stretching factor of the upper disk. The tangential velocity distribution augments with the increasing rotation parameter. In comparison to nanofluid, hybrid nanofluid has stronger effects of the embedded factors on its Nusselt and Sherwood numbers at the lower disk, whereas at the upper disk, nanofluid has more effects of the embedded factors on its Nusselt and Sherwood numbers. This research might have an impact on various gadgets, including those that use air conditioning, chemicals and electronics. It is anticipated that the findings of this study will complement previously published work as well as provide information on engineering and industrial applications.
