Exact Analytical Solution for Large-Amplitude Oscillatory Shear Flow
When polymeric liquids undergo large-amplitude shearing oscillations, the shear stress responds as a Fourier series, the higher harmonics of which are caused by fluid nonlinearity. Previous work on large-amplitude oscillatory ...
Polymer Orientation Contributions in Large-Amplitude Oscillatory Shear Flow
Previously, we used a dilute suspension of rigid dumbbells as a model for the dynamics for polymeric liquids in large-amplitude oscillatory shear (LAOS) flow. We then use dumbbell orientation to explain fluid elasticity. ...
Review of Nonlinear Oscillatory Shear Flow Notations and Presentations: Polymeric Liquids
We review notations for, along with ways of presenting, the shear stress responses to large-amplitude oscillatory shear flow (LAOS). We find that the Fourier loss and storage viscosities to be the simplest primal notations ...
Fourier Decomposition of Polymer Orientation in Large-Amplitude Oscillatory Shear Flow
In our previous work, we explored the dynamics of a dilute suspension of rigid dumbbells as a model for polymeric liquids in large-amplitude oscillatory shear flow, a flow experiment that has gained a significant following ...
