The main theme of the present study is to analyze numerically the effects of the magnetic field on the hybrid nanofluid flow over a flat elastic surface. The effects of the thermal and velocity slips are also analyzed in view of the hybrid nanofluid flow. It is considered a combination of titanium oxide (TiO2) and copper oxide (CuO) nanoparticles that are suspended in the incompressible and electrically conducting fluid (water). The behavior of the Brownian motion of the nanoparticles and the thermophoretic forces are contemplated in the physical and mathematical formulations. Moreover, the impact of the Joule heating and viscous dissipation are also discussed using the energy equation. The mathematical modeling is simulated with the help of similarity variables. The resulting equations are solved using the Keller–Box method with a combination of finite difference schemes (FDSs). Hybrid nanofluids provide significant advantages over the usual heat transfer fluids. Therefore, the use of nanofluids is beneficial to improve the thermophysical properties of the working fluid. All of the results are discussed for the various physical parameters involved in governing the flow. From the graphical results, it is found that the hybrid nanoparticles improve the concentration, temperature, and velocity profiles, as well as the thickness of the relevant boundary layer. The conjunction of a magnetic field and the velocity slip, strongly opposes the fluid motion. The boundary layer thickness and concentration profile are significantly reduced with the higher levels of the Schmidt number.

“…Particles with nano-sized are added to enhance these features of a basic fluid. Many researchers have examined nanofluids together with corrugated ducts [22][23][24]. Manca et al [25] examined the thermal characteristics of water based Al2O3 nanofluid for different particle volume fractions (0 ≤ φ ≤ 0.04) in a duct with varying rib heights and declared that thermal performance improved with increasing the Re and φ.…”

This study numerically focused investigating the thermal performance of flow oscillations in a rectangular corrugated channel with vertical plates on top wall. The numerical study was performed with the ANSYS Fluent software, and the SIMPLE algorithm was utilized to solve the pressure-velocity coupling. The top wall of the channel was adiabatic and included vertical plates. The bottom wall of the channel was rectangular grooved and kept at Tw=360 K. Suspension of Al2O3 nanoparticles into water was used as the fluid. The particle volume fraction in the suspension was kept constant at φ = 5%. Oscillating amplitude (A) and Strouhal number (St) were maintained constant at A = 1 and St = 2, respectively. In the presented study, the effects of vertical plates, Al2O3-water nanofluid and pulsating flow on flow and heat transfer were analyzed separately at different Reynolds numbers (200 ≤ Re ≤ 800). The Nusselt number (Nu), relative friction factor (frel) and performance evaluation criteria (PEC) were obtained for different Reynolds numbers. The temperature and velocity fields were acquired for varying parameters. The results demonstrated that the flow and temperature structures were significantly influenced by the channel geometry and oscillating flow. Heat transfer considerably enhanced with the oscillating flow at the high Re. At Re = 800, thermal improvement for oscillating flow of the nanofluid in the channel with plates increased by nearly 1.57 times relative to the steady case of the basic fluid in the channel without plates.

“…Rabiei et al 9 numerically showed that shifting the working fluid from water to graphene–platinum–water hybrid nanofluid improved the microchannel heat sink efficiency by augmenting the thermal conductivity of the base liquid. Newly, Alawi et al experimentally 10 studied the hybrid nanofluid flow of MWCNT/TiO2/H2O within a corrugated channel and have shown that the transport of heat is augmented by 26% when nanoparticles weight concentrations is increased by 0.1%. Using hybrid nanofluid (single-walled carbon nanotubes-silver/gasoline oil), Muhammad et al 11 numerically investigated the flow within the boundary layer and melting heat transport along with the thickness stretch effect.…”

In this study, the Caputo space-fractional derivatives of energy equation are used to model the heat transfer of hybrid nanofluid flow along a plate. The plate is considered permeable and affected by an inclined magnetic field. We use the space-fractional derivative of Fourier’s law to communicate between the nonlocal temperature gradient and heat flux. The hybrid nanofluid is formed by dispersing graphene oxide and silver nanoparticles in water. The new fractional integro-differential boundary layer equations are reduced to ordinary nonlinear equations utilizing suitable normalizations and solved via a novel semi-analytical approach, namely the optimized collocation method. The results reveal that the increment of the order of space-fractional derivatives and the magnetic inclination angle increase the Nusselt number. Also, an increase in the order of space-fractional derivatives leads to a thicker thermal boundary layer thickness resulting in a higher temperature. It is also found that the temperature of the fluid rises by changing the working fluid from pure water to single nanofluid and hybrid nanofluid, respectively. What is more, the proposed semi-analytical method will be beneficial to future research in fractional boundary layer problems.
