Perspectives on viscoelastic flow instabilities and elastic turbulence
Sujit S. Datta, Arezoo M. Ardekani, Paulo E. Arratia +20
Viscoelastic fluids are a common subclass of rheologically complex materials that are encountered in diverse fields from biology to polymer processing. Often the flows of viscoelas…
Single-shot quantitative polarization imaging of complex birefringent structure dynamics
Baoliang Ge, Qing Zhang, Rui Zhang +8
Polarization light microscopes are powerful tools for probing molecular order and orientation in birefringent materials. While a multitude of polarization light microscopy techniqu…
Two Modes of Cluster Dynamics Govern the Viscoelasticity of Colloidal Gels
Jae Hyung Cho, Irmgard Bischofberger
Colloidal gels formed by strongly attractive particles at low particle volume fractions are composed of space-spanning networks of uniformly sized clusters. We study the thermal fl…
Growth morphology and symmetry selection of interfacial instabilities in anisotropic environments
Qing Zhang, Amin Amooie, Martin Z. Bazant +1
The displacement of a fluid by another less viscous one in a quasi-two dimensional geometry typically leads to complex fingering patterns. In an isotropic system, dense-branching g…
Criterion for fingering instabilities in colloidal gels
Thibaut Divoux, Asheesh Shukla, Badis Marsit +2
We sandwich a colloidal gel between two parallel plates and induce a radial flow by lifting the upper plate at a constant velocity. Two distinct scenarios result from such a tensil…
Emergence of Multiscale Dynamics in Colloidal Gels
Jae Hyung Cho, Roberto Cerbino, Irmgard Bischofberger
To gain insight into the kinetics of colloidal gel evolution at low particle volume fractions , we utilize differential dynamic microscopy to investigate particle aggregation, g…
