Soret and Dufour effects on peristaltic transport in curved channel with radial magnetic field and convective conditions

Abstract This study addresses the impact of convective heat and mass conditions in the peristaltic transport of fluid in a complaint wall curved channel. Formulation for flow of third grade fluid is made. Soret and Dufour effects are considered. Fluid is conducting through applied magnetic field in radial direction. Lubrication approach is employed. Solutions for stream function, temperature and concentration fields are derived. The effects of pertinent parameters in the solutions are analyzed graphically. It is found that the velocity profile is not symmetric about the central line in curved channel. The velocity and temperature are reduced by increasing magnetic field strength. The number and size of streamlines are decreased in the presence of magnetic field effect.
