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 the stagnation point flow towards a curved surface. Silica (SiO2) and alumina (Al2O3) nanoparticles are added into water to form SiO2 Al2O3/water hybrid nanofluid. Both buoyancy-opposing and -assisting flows are considered. The governing part...
