Abstract

Laminar boundary layer flow of Williamson fluid over a moving plate is discussed in this paper. The governing equations of the flow problem are transformed into similarity equations using similarity technique. The reduced equations are numerically solved by finite difference method. The graphical presentation is discussed.

Summary

Introduction

Non-Newtonian fluids are types of pseudo-plastic fluids. Wide range of industrial application like suspension coated sheets (photographic films), high molecular weight polymers melts and its solutions etc. All the rheological properties of such types of fluids are not explained by the Navier-Stokes equations To overcome this type of deficiency, different types of fluid models has been proposed by researchers. Dapra and Scarpi (2007) considered Williamson fluid injected into a rock fracture and gives the perturbation solution. Nadeem et al (2010) discussed peristaltic flow of a Williamson fluid. Srivastava et al (1995, 2007) discussed the flow in nonuniform geometry and gives theoretical model under the effects of an inserted endoscope on Chyme movement in small intestine. Nadeem et al (2013) find the solution flow of a Williamson Fluid over a stretching sheet by applying homotopy analysis method (HAM). (2007) discussed perturbation solution for pustule flow of a non-Newtonian Williamson fluid in a rock fracture.
