MHD peristaltic transport of Eyring–Powell fluid with heat/mass transfer, wall properties and slip conditions

Abstract

Present work explores the combined influence of slip and magnetohydrodynamics on the peristaltic motion of Eyring–Powell fluid in a complaint wall channel with heat/mass transfer. Viscous dissipation effects are also considered. Adequate assumptions of long wavelength and low Reynolds number are employed. Series solutions for small fluid parameter are developed by regular perturbation approach. The expressions for the axial velocity, temperature distribution, concentration distribution and stream function are determined. Graphical results are presented to analyze the behavior of the parameters entering in the problem. It is observed that Eyring–Powell fluid parameters have significant role on the solutions. Temperature increases and heat transfer coefficient enlarges when viscous dissipation effect is intensified. Heat transfer coefficient has inverse relationship with both magnetic field and velocity slip parameters.
