Peristaltic transport of Powell-Eyring fluid in a curved channel with heat/mass transfer and wall properties

In this work, we explore the peristaltic flow of Powell-Eyring fluid through curved passage with complaint walls. Heat and mass transfer analyses in the presence of viscous dissipation and thermophoresis effects are performed. Adequate assumptions of long wavelength and low Reynolds number are accounted for problem formulation. The arising system of partial differential equations is solved by using regular perturbation method. Our results show that the material parameters of the Powell-Eyring fluid strongly affect the flow fields. We observe that symmetry in the profiles is not preserved in the curved channel. The size and shape of the trapped bolus is different in the upper and lower halves of the curved channel. A comparative study of curved and planar channels is also presented. (C) 2016 Elsevier Ltd.
