COMBINED EFFECTS OF HALL CURRENT, WALL SLIP, VISCOUS DISSIPATION AND SORET EFFECT ON MHD JEFFREY FLUID FLOW IN A VERTICAL CHANNEL WITH PERISTALSIS

摘要

This paper investigates peristaltic motion of an MHD Jeffrey fluid in a vertical asymmetric channel with wall slip and Hall current. The channel asymmetry is caused due to peristaltic wave train on the walls having different amplitudes and phase. Assumptions of long wavelength and low Reynolds number are used to obtain solution for the problem. Closed form expressions for the stream function, temperature and concentration are developed. Pressure rise per wavelength and frictional forces on the channel walls have been computed numerically. The physical significance of interesting parameters on heat and mass transfer characteristics of the fluid flow is shown through graphs and discussed in detail.
