Hall and ohmic heating effects on the peristaltic transport of a carreau-yasuda fluid in an asymmetric channel

Abstract

The effects of Hall current and Ohmic heating are analyzed for the peristaltic flow of a Carreau-Yasuda fluid in an asymmetric channel. The mathematical model for peristalsis of the Carreau-Yasuda fluid is provided for the first time in the literature. The problem is developed in the presence of viscous dissipation. Solutions for pressure gradient, stream function, axial velocity, and temperature are established and discussed. The heat transfer rate at the wall is first computed numerically and then examined. A comparative study for viscous, Carreau, and Carreau-Yasuda fluids is also made. ©2014 Verlag der Zeitschrift für Naturforschung, Tübingen.
