Abstract

In this paper, we present the analysis of the blade coating process of an incompressible Powell-Eyring fluid which serves as a lubricant. The application of the lubrication approximation theory (LAT) has been utilized for simplification of the equations of the motion. For the investigation of the nature of the steady solution which exist, we make use of perturbation technique and numerical method. The solution expressions of the velocity profile, pressure gradient, rate of volumetric flow, shear stresses at the walls y = 0 and y = h, and distribution of pressure are obtained. Some of the results are presented graphically whereas the tabulated forms are given for the others. Here it has been observed that only non-Newtonian and viscous terms are having affects, where as the inertial term is negligible. Taking the non-Newtonian affects smaller than the viscous ones, the approximate perturbation solution is calculated.
