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.

Summary
The observation of magnetohydrodynamic (MHD) flow behavior is essential in diverse fields of engineering and has attracted considerable attention due to its significance in industrial applications, for instance in fossil-fueled power generation [1]. The groundbreaking work on numerical analysis of mixed convection stagnation point flow past heated vertical flat surfaces was performed by Ramachandran et al [10]. Chamkha [32] studied continuous, two-dimensional, MHD mixed convection flows near a stagnation point of an electrically conducting and heat-absorbing fluid on a semi-infinite vertical permeable surface with arbitrary variations of surface heat flux. Abdelkhalek [33] performed a numerical analysis to examine the impact of mass transfer in MHD mixed convection in view of stagnation point flow over a heated vertical permeable sheet. The overarching focus of this study is to conduct an analysis on unsteady MHD mixed convection stagnation point in the three-dimensional flow of alumina-copper/water hybrid nanofluid with stability analysis. This major participation will lead to stimulating industrial progress, in the engineering and manufacturing sectors
