    Abstract

    The effect of velocity slip, temperature and concentration jump conditions on the MHD peristaltic flow of a Carreau fluid in a non-uniform channel with heat and mass transfer is investigated. Using a perturbation technique, for small Weissenberg number, solutions are obtained for the non-linear differential equations with appropriate boundary conditions. The expressions for the stream function, velocity, temperature and concentration fields; and the heat transfer coefficient are obtained. The effects of the physical parameters on the velocity and temperature fields are presented through graphs, and are discussed. Also, the trapping phenomenon is analyzed. It is observed that the size of the trapping bolus increase with an increase in the velocity slip parameter beta(1). (C) 2013 Elsevier Inc. All rights reserved.
