Flow towards a Stagnation Region of a Curved Surface in a Hybrid Nanofluid with Buoyancy Effects

This paper examines the impact of hybrid nanoparticles on stagnation point flow towards a curved surface. Silica (SiO2) and alumina (Al2O3) are added into water to form SiO2-Al2O3/water nanofluid. Both buoyancy-opposing -assisting flows considered. The governing partial differential equations reduced set ordinary equations, before being coded in MATLAB software obtain numerical solutions. Findings show that solutions not unique, where two obtained, for both buoyancy-assisting -opposing cases. local Nusselt number increases presence nanoparticles. temporal stability analysis shows only one is stable over time.
