EFFECT OF THE VELOCITY SECOND SLIP BOUNDARY CONDITION ON THE PERISTALTIC PUMPING OF COUPLE-STRESS FLUID FLOW WITH THERMAL PROPERTIES IN AN ASYMMETRIC CHANNEL

摘要

The heat transfer characteristics of a couple-stress fluid in an asymmetric channel in the presence of the second order slip boundary condition were investigated in this paper. The channel asymmetry is produced by peristaltic wave train on the walls to have different amplitudes and phase. The system governing current flow was found as a set of non-linear PDE, which are solved and the analytical expression for the axial velocity, stream function, pressure gradient and pressure rise are established using long wavelength and low Reynolds number assumptions. The effect of second slip parameter on the present physical parameters was discussed through graphs and the importance of this type of slip is discussed in detail.
