Self-Consistent Fourier-Tschebyshev Representations of the First Normal Stress Difference in Large Amplitude Oscillatory Shear
Nicholas King, Eugene Pashkovski, Reid Patterson +2
Large Amplitude Oscillatory Shear (LAOS) is a key technique for characterizing nonlinear viscoelasticity in a wide range of materials. Most research to date has focused on the shea…

Elasto-Inertial Instability in Torsional Flows of Shear-Thinning Viscoelastic Fluids
Rishabh V. More, Eugene Pashkovski, Reid Patterson +1
It is well known that inertia-free shearing flows of a viscoelastic fluid with curved streamlines, such as the torsional flow between a rotating cone and plate, or the flow in a Ta…

Rod-climbing rheometry revisited
Rishabh V. More, Reid Patterson, Eugene Pashkovski +1
The rod-climbing or Weissenberg effect in which the free surface of a complex fluid climbs a thin rotating rod is a popular and convincing experiment demonstrating the existence of…
