The Effect of the Couple Stress Fluid Flow on MHD Peristaltic Motion with Uniform Porous Medium in the Presence of Slip Effect

The present paper investigates the effects of the couple stress fluid flow on the magnetohydrodynamic peristaltic motion with a uniform porous medium in the presence of slip effect. The analysis is carried out under the assumption of long wavelength approximations. Expressions of the axial velocity, transverse velocity, pressure gradient, volume flow rate, average volume flow rate, pressure rise and shear stress are all obtained. The effects of various emerging axial velocity, transverse velocity, pressure gradient shear stress are discussed through graphs. It was observed that the velocity distribution (u) decreased by increasing the couple stress parameter (S) with beta >= 0.2; we also noticed that the transverse velocity increased by increasing the couple stress parameter (S) >= 0.2. We noticed that the pressure gradient decreased by increasing the slip parameter (beta). (C) 2015 Jordan Journal of Mechanical and Industrial Engineering. All rights reserved
