A minimal model for chaotic shear banding in shear-thickening fluids
A. Aradian, M. E. Cates
We present a minimal model for spatiotemporal oscillation and rheochaos in shear-thickening complex fluids at zero Reynolds number. In the model, a tendency towards inhomogeneous f…
Instability and spatiotemporal rheochaos in a shear-thickening fluid model
A. Aradian, M. E. Cates
We model a shear-thickening fluid that combines a tendency to form inhomogeneous, shear-banded flows with a slow relaxational dynamics for fluid microstructure. The interplay betwe…
Flow instabilities in complex fluids: Nonlinear rheology and slow relaxations
A. Aradian, M. E. Cates
We here present two simplified models aimed at describing the long-term, irregular behaviours observed in the rheological response of certain complex fluids, such as periodic oscil…
Interfacial layering in a three-component polymer system
A. Aradian, F. Saulnier, E. Raphael +1
We study theoretically the temporal evolution and the spatial structure of the interface between two polymer melts involving three different species (A, A* and B). The first melt i…
Adhesion between a viscoelastic material and a solid surface
F. Saulnier, T. Ondarcuhu, A. Aradian +1
In this paper, we present a qualitative analysis of the dissipative processes during the failure of the interface between a viscoelastic polymer and a solid surface. We reassess th…
A Scaling Theory of the Competition between Interdiffusion and Cross-Linking at Polymer Interfaces
Achod Aradian, Elie Raphael, Pierre-Gilles de Gennes
We study theoretically situations where competition arises between an interdiffusion process and a cross-linking chemical reaction at interfaces between pieces of the same polymer…
