Rotating Hybrid Nanofluid Flow with Chemical Reaction and Thermal Radiation between Parallel Plates

Abstract

This research investigates the two different hybrid nanofluid flows between two parallel plates placed at two different heights, y0 and yh, respectively. Water-based hybrid nanofluids are obtained by using Al2O3, TiO2 and Cu as nanoparticles, respectively. The upper-level plate is fixed, while the lower-level plate is stretchable. The fluid rotates along the y-axis with constant speed Ω. The governing equations of momentum, energy and concentration are transformed into partial differential equations by using similarity transformations. These transformed equations are grasped numerically at MATLAB by using the boundary value problem technique. The influence of different parameters are presented through graphs. The numerical outcomes for rotation, Nusselt, Prandtl, and Schmidt numbers are obtained in the form of tables. The heat transfer rate increases by augmentation in the thermophoresis parameter, while it decays by increasing the Reynolds number. Oxide nanoparticles hybrid nanofluid proved more efficient as compared to mixed nanoparticles hybrid nanofluid. This research suggests using oxide nanoparticles for good heat transfer.

“…The above-conducted literature review suggests that numerous researchers have investigated the flow past the stretching surface. Arshad 53 explored the thermophoresis and Brownian motion with thermal radiative effect and uniform magnetic field. Arshad 47 investigated the chemical reaction effect over an exponential stretching surface.…”

“…The novelty of this paper is to investigate the comparative dynamics of rotating water-based nano and hybrid nanofluids over dual stretching surfaces implanted in a permeable medium with radiative heat and mass transfer. Arshad 47 , 53 examined a uniform magnetic field, whereas in this study we have incorporated an inclined magnetic field with a chemical reaction. The prevailing equations are changed into the ordinary differential equation by employing a similarity transformation and attempted MATLAB by utilizing the boundary value problem method.…”
