Extensional Viscosity

In enhanced oil recovery processes, the extensional properties of the viscoelastic fluids frequently exhibit strong extensional thickening well beyond the Trouton ratio for Newtonian fluids. In order to predict the process conditions that will optimize fluid flow or characterize the final product, a thorough rheological characterization of materials in both shear and extensional flow conditions is recommended.
