Webinar Download - Extensional Viscosity with e-VROC: Data Analysis & Interpretation


In May 2021 we presented the theory behind the e-VROC® extensional viscometer, as well as practical guidance to perform experiments.

Download this webinar for a follow up discussion on extensional viscosity data analysis and interpretation. The following topics will be covered: 

  • Recalling that e-VROC® is a mixed flow environment, we will illustrate how to calculate steady shear viscosity from the data in addition to the extensional.
  • Demonstrate how the steady shear viscosity can be used to confirm chip performance.
  • Correct the pressure drop across the hyperbolic contraction to emphasize the extensional component of the flow field.
  • Utilize dimensionless groups such as the Reynolds number to facilitate data interpretation.
