Slip and porosity effects on peristalsis of MHD Ree-Eyring nanofluid in curved geometry

Abstract

The present framework intends to present a comprehensive study that relates the innovative idea of porous media followed by modified Darcy’s law. Nanofluid flow has been investigated with Ree-Eyring as base fluid model. The contraction and relaxation of smooth muscle stems the peristaltic waves that induce the flow along the curved channel. The flow kinetics further involve variable viscosity, magnetohydrodynamics, viscous dissipation and thermo-diffusion (Soret) effects. The adherence condition (slip condition) in terms of velocity, temperature and concentration is retained. The curved channel walls are flexible. The resulting nonlinear PDEs are transformed into ODEs via lubrication approach. The striking features of flow, temperature and mass transfer outcomes under the involved parameters are examined by plotting graphs.
