Theoretical study of transport of MHD peristaltic flow of fluid under the impact of viscous dissipation

This article studies irreversibility analysis in the peristaltic transport of a non-Newtonian fluid. Jeffrey fluid is treated as the blood transport through a flexible artery/vessel. A peristaltic wave travels on the porous opposite wall of the inclined channel under the magnetic environment. Heating effects cause the shear thinning in the viscosity of the base liquid, transferring tiny particles. The efficiency of peristalsis is improved by reducing the irreversibility factor by means of entropy generation. The perturbation technique is applied to understand the nonlinear flow dynamics of heat and mass transfer with Jeffrey fluid with the help of convective boundary conditions. Comparative analysis is carried out with the available literature for the limiting case and found to have complete coherence. A detailed parametric study is carried out to comprehend the contribution of significant parameters which reveals that magnetic fields and slippery walls induce a resistive force on the nanoflow. The motion of the base liquid expedites subject to variation in Darcy number and shear-thinning effects. The energy is contributed to the nanofluid system in response to the Brinkman number. More, the number density of nanospecies reduces in the region of higher concentration subject to the Soret number and Schmidt number, respectively.
