Multiple solutions and stability analysis of magnetic hybrid nanofluid flow over a rotating disk with heat generation

This study highlights the hybrid Fe3O4-CoFe2O4/H2O ferrofluid flow and heat transfer with the effects of linear heat generation, magnetic field and suction on a rotating disk. Using the similarity transformation, the mathematical model is simplified and reduced to a similarity set of equations. Th...
