Unsteady Three-Dimensional Flow in a Rotating Hybrid Nanofluid over a Stretching Sheet

Abstract

The problem of an unsteady 3D boundary layer flow induced by a stretching sheet in a rotating hybrid nanofluid is studied. A dimensionless set of variables is employed to transform the system of partial differential equations (PDEs) to a set of nonlinear ordinary differential equations (ODEs). Then, the system of ODEs is solved numerically using the MATLAB software. The impacts of different parameters, such as copper nanoparticles volume fraction, radiation, rotation, unsteadiness, and stretching parameters are graphically displayed. It is found that two solutions exist for the flow induced by the stretching sheet. Furthermore, the increasing nanoparticle volume fraction enhances the skin friction coefficient. It is noticed that the skin friction coefficient, as well as the heat transfer rate at the surface, decrease as the rotating parameter increases. Additionally, the thermal radiation as well as the unsteadiness parameter stimulate the temperature.

Comparative study of some non-Newtonian nanofluid models across stretching sheet: a case of linear radiation and activation energy effects

“…Using nanofluids on a linear surface to generate boundary flows presents several benefits for engineering and industrial purposes. According to 5 , nanofluids can improve thermal efficiency, acceleration of processes, and extension of equipment lifespan. The structural characteristics of nanoparticles, which resemble those of solids, promote the transmission of nanofluids.…”

Dual solutions for general three-dimensional MHD boundary layer stagnation-point flow of hybrid nanofluid and heat transfer

“…In an evaluation of stagnation point flow over a circular cylinder in three dimensions, Nadeem et al (2018) found that thermal performance improved with increasing concentrations of copper nanoparticles. Meanwhile, Zainal et al (2020) and Mohd Sohut et al (2022) investigated the unsteady hybrid nanofluid flow towards a stretching/shrinking surface in the stagnation region and rotating fluid, respectively. In addition, the following collection of published articles contains references to recent studies and new modeling concerning nanofluid and hybrid nanofluid convective flows (Dinarvand and Nejad, 2021; Pop et al , 2021; Mansourian et al , 2022).…”
