Abstract
The goal of this study is to investigate the effect of couple stress on Powell-Eyring fluid peristaltic transport in an inclined asymmetric channel using porous medium. Peristaltic motion of a magnetohydrodynamic Powell-Eyring fluid in inclined asymmetric channel with porous medium, medium is investigated in the present study. The modeling of mathematic is created in the presence of effect of couple stress, using constitutive equations following the Powell-Eyring fluid model. In flow analysis, assumptions such as long wave length approximation and low Reynolds number are utilized. Closed form formulas for the stream function and mechanical efficiency are created. On the channel walls, pressure rise per wave length has been calculated numerically. The effects of the Hartman number (Ha), Darcy number (Da), material fluid parameter (w), inclination of magnetic field (β), amplitude ratio (∅), The effects of the Couple Stress on axial velocity and entrapment are investigated in detail and graphically shown.
