Rheology of Dissemination.

Abstract

Although large extensional flow components occur in many technological processes of liquids, there is no currently suitable device to measure the elongational properties of polymer solutions. This report describes a possible method of inferring extensional fluid properties by determining the nonlinear, time-dependent mechanical properties of concentrated solutions of polymers from stress relaxation in torsion measurements. This method is based on the BKZ model of an isothermal elastic fluid with an elastic potential function of the Valanis Landel type. Originator-supplied keywords include: BKZ model, Liquid breakup, Polymer solutions, Mechanical properties, Extensional flow, Fluid rheology; Stress relaxation, and Elastic potential function.
