Wall properties and convective conditions in MHD radiative peristalsis flow of Eyring–Powell nanofluid

Abstract

Present study examines the impacts of wall flexibility on MHD peristaltic flow of Eyring–Powell nanofluid with convective conditions. No slip conditions are imposed on channel walls. Analysis is made in presence of Joule heating and radiation aspects. Viscous dissipation effects are also analyzed. Nanofluid model is considered by taking the impacts of thermophoresis and Brownian motion. Lubrication approach (large wavelength and low Reynolds number) is taken into account for the simplicity of problem. Numerical technique is utilized for the solution. Influence of pertinent variables on quantities of interest (axial velocity, temperature, concentration and coefficient of heat transfer) is inspected graphically. The larger magnetic field corresponds to a decay in velocity while Eyring–Powell fluid parameters for velocity and temperature show the opposite impact. Brownian motion and thermophoresis impacts yield an increment in temperature and heat transfer coefficient. Reverse behavior is observed for radiation on temperature and concentration.
