Coriolis effects on MHD flow of MEP fluid over a non-uniform surface in the presence of thermal radiation

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.

Automated summary

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.
