Overview

Dr Heywood has been involved in the measurement of and applications for fluid rheology to process engineering applications since 1973. His talk on general aspects of fluid rheology will cover the definition of rheology and viscosity, Newtonian vs. non-Newtonian behaviour, whether information on fluid viscosity is always needed for fluid flow design, and how to measure flow curves (rheograms) under the correct test conditions for given applications. In addition, other rheological properties will be covered including yield stress, time-dependent properties (eg thixotropy), and some interesting phenomena associated with viscoelasticity.
