Unsteady MHD Mixed Convection Flow in Hybrid Nanofluid at Three-Dimensional Stagnation Point

Abstract

There has been significant interest in exploring a stagnation point flow due to its numerous potential uses in engineering applications such as cooling of nuclear reactors. Hence, this study proposed a numerical analysis on the unsteady magnetohydrodynamic (MHD) mixed convection at three-dimensional stagnation point flow in Al2O3–Cu/H2O hybrid nanofluid over a permeable sheet. The ordinary differential equations are accomplished by simplifying the governing partial differential equations through suitable similarity transformation. The numerical computation is established by the MATLAB system software using the bvp4c technique. The bvp4c procedure is excellent in providing more than one solution once sufficient predictions are visible. The influence of certain functioning parameters is inspected, and notable results exposed that the rate of heat transfer is exaggerated along with the skin friction coefficient while the suction/injection and magnetic parameters are intensified. The results also signified that the rise in the volume fraction of the nanoparticle and the decline of the unsteadiness parameter demonstrates a downward attribution towards the heat transfer performance and skin friction coefficient. Conclusively, the observations are confirmed to have multiple solutions, which eventually contribute to an investigation of the analysis of the solution stability, thereby justifying the viability of the first solution.

“…The enrichment of heat transfer by scattering water-based aluminum oxide and copper hybrid nanoparticles induced via a stretchable sheet was inspected by Devi and Devi (2016). The time-dependent flow with heat transport in hybrid nanoparticles toward various surfaces was considered by Khan et al (2021a); Waini et al (2019, 2021a); Khashi’ie et al (2020); and Zainal et al (2021a). They reported double solutions for an assured range of physical parameters.…”

“…Waini et al (2020) investigated thermal performance towards a permeable moving wedge while taking magnetic parameter execution into consideration in hybrid nanofluid. The influence of magnetohydrodynamics (MHD) stagnation point flow on a permeable moving surface with buoyancy effect is addressed by Hussain et al (2021); Zainal et al (2020a, 2021a); and Jamaludin et al (2020). Some available reviews focused on the nanofluid and hybrid nanofluid considering various effects can be assessed through Uddin et al (2015), Ghalambaz et al (2019); Waini et al (2021a); Zainal et al (2021b); Roşca et al (2021a, 2021b, 2021c); and Khan et al (2021).…”

Thermal mechanism in magneto radiated [(Al2O3-Fe3O4)/blood]hnf over a 3D surface: Applications in Biomedical Engineering

“…Alshare et al ( Alshare et al, 2020 ) investigated the nano and hybrid nanofluid heat transport mechanisms in a periodic structure and found that enhancing % volume fraction will result increment in the temperature and frictional effects. A numerical analysis of an unsteady MHD mixed convection ( Khan, Adnan, and Haleema, 2022 ) stagnation point flow heat transmission model (SPFM) for Cu-Al 2 O 3 /water over a 3D oriented geometry is described in Zainal et al, 2021 . Nur et al ( Wahid et al, 2020 ) examined an analytic solution under slip momentum and thermal radiation influences on magnetized Cu-Al 2 O 3 /water nanofluid over a permeable stretching sheet ( Adnan et al, 2022a ).…”
