Consequences of variable thermal conductivity and activation energy on peristalsis in curved configuration

Here peristalsis of non-Newtonian liquid in the presence of heat and mass transfer is examined. Mathematical formulation is developed in view of viscous dissipation, variable thermal conductivity and activation energy. Lubrication approach is adopted to retain mathematical modeling in tractable form. Series solution via small Weissenberg is obtained for momentum equation while temperature and concentration equations are solved numerically via built-in shooting technique. The obtained series solutions for pressure gradient, pressure rise per wavelength, stream function, velocity and numerical solutions for temperature, concentration and rates of heat and mass transfer are validated via graphical presentations. Discussion is made in detail. It is observed from the graphical results that pressure rise per wavelength and pressure gradient have opposite behavior for Wessienberg and Johnson-Segalman fluid slip factor parameters. It is reported that due to increasing impact of activation energy parameter concentration enhances whereas opposite impact of chemical reaction parameter on concentration is noted.
