This study investigates the flow of electrically conducting Eyring-Powell fluid over a rotating surface, with findings suggesting that the properties of the fluid can be modulated by modifying a specific parameter. Numerical simulations show that the primary velocity decreases with increasing rotation, magnetic field strength, and MEP parameter, but increases with velocity index.
The study of electrically conducting Eyring-Powell fluid flow across a rotating surface has practical applications in the exploitation of liquid metals, manufacturing of ship propellant, production of paints, greases, and toothpaste. The Modified Eyring-Powell (MEP) fluid is the Eyring-Powell fluid equipped with a parameter that regulates the shear thickening and shear thinning properties. In this paper, MEP flow is investigated over a rotating and stretching surface under the influence of thermal radiation and magnetic field. The model that governs the flow of electrically conducting MEP fluid over a stretching rotating surface with non-uniform thickness in the presence of thermal radiation is formulated and non-dimensionalised. The dimensionless governing equations are solved numerically; with the results depicted as graphs. It is found that the primary velocity is reduced with increasing rotation, magnetic field strength and MEP parameter but increases with velocity index.
