Abstract
This article examined Soret and Dufour effects on peristaltic transport of an Oldroyd 8-constants fluid in a curved channel. Aspects, of mixed convection and radially applied magnetic field are considered. Convective conditions of heat and mass transfer at the channel walls are imposed. Governing problems for velocity, temperature and concentration are reduced for long wavelength and low Reynolds number considerations. Resulting problems are analyzed numerically. Specifically the analysis velocity, temperature, concentration and heat transfer coefficient are focused for the emerging parameters. It is noticed that axial velocity enhances for larger material parameter of fluid. Impact of mixed convection decays axial velocity. Furthermore temperature and concentration have opposite behavior for Soret and Dufour numbers. (C) 2016 Elsevier Masson SAS. All rights reserved.
