Description
Summary:The current article investigates the magnetohydrodynamic (MHD) radiative peristaltic flow of a couple stress nanoliquid in a symmetric channel. Thermally convective and zero mass flux conditions are imposed on flexible channel walls. Impacts of Joule heating and viscous dissipation are considered. Nanofluid model consists of important features Brownian motion and thermophoresis. First‐order chemical reaction is present in mass transportation. The resulting system of differential equations is numerically tackled after adopting large wavelength and low Reynolds number assumptions. Influences of pertinent variables of interest on concentration, temperature, coefficient of heat transfer, streamlines, skin friction coefficient, and Nusselt and Sherwood numbers are examined graphically. The findings of this study reveal that temperature enhances against Brownian motion and thermophoresis parameters, whereas it decays for radiation variable. Concentration of the fluid declines for a couple stress fluid variable. Further, the heat transfer coefficient shows increasing behavior for Eckert number.
