On electroosmosis in peristaltic activity of MHD non-Newtonian fluid

Abstract

Electroosmosis in peristalsis of non-Newtonian fluid in a microchannel is considered. Magnetohydrodynamics (MHD), thermal radiation and mixed convection are adopted. Momentum, mass and temperature equations for third grade fluid are derived for long wavelength and small Reynolds number. Formulation is further completed by considering the velocity, temperature and concentration slip conditions. An internal energy generation is also taken into account. The physical parameters involved in flow characteristics are graphically analyzed. This work finds its utility in micro-fabrication technique, reservoir engineering and chemical industry where the electro-osmotic energy and mass exchanges play a vital role.
