Hybrid nanofluid flow with homogeneous-heterogeneous reactions

This study examines the stagnation point flow over a stretching/ shrinking sheet in a hybrid nanofluid with homogeneous-heterogeneous reactions. The hybrid nanofluid consists of copper (Cu) and alumina (Al2O3) nanoparticles which are added into water to form Cu-Al2O3/water hybrid nanofluid. The simi...
