Electromagnetic effects on two-layer peristalsis flow of Powell–Eyring nanofluid in axisymmetric channel

The current analysis reveals unreported properties of the two-layer flow of dual convective magneto-hydrodynamic viscous nanofluid and Powell–Eyring in flexible concentric cylinders in the existing literature. The transmission of two immiscible fluids involving viscous nanofluid in the peripheral region and Powell–Eyring fluid in the core region is analyzed. The flow is induced by a sinusoidal wave that is propagated on the compliant wall. Over the outer cylinder, concentration and temperature are supposed to be greater than in the inner cylinder. The fluid flow of each phase involves continuity equation, momentum, heat transfer and mass transfer equations with the addition of electromagnetic effect. At interface, the continuity of velocity, stress, temperature are considered. In order to construct the model that includes mass and heat transport for both regions, long wavelength and creeping flow are assumed. The calculations are made against the resultant equations by using homotopy perturbation method. The outcomes of simulation for significant physical parameters are described and illustrated graphically. The graphical analysis shows that the electric and magnetic parameter changes in opposite manner for both temperature and velocity profiles. Both regions exhibit an increase in fluid temperature along with a rise in Brickman number.
