About this document
Viscosity and Normal Stress in Shear Flow by Azizol Wahab is a document available to read on EtoBox.
This document discusses viscosity and normal stress differences in viscoelastic fluids under viscometric flows. It defines viscosity as relating shear stress to shear rate in simple shear flow. For viscoelastic fluids, two additional properties called normal stress differences are needed to describe the stress field. Common viscometric flows include steady tube flow, slit flow, concentric cylinder flow, parallel disk flow, and combined drag and pressure flows. Viscosity and normal stress differences depend
