Polymer stretching in laminar and random flows: entropic characterization
Stefano Musacchio, Victor Steinberg, Dario Vincenzi
Polymers in nonuniform flows undergo strong deformation, which in the presence of persistent stretching can result in the coil-stretch transition. This phenomenon has been characte…
Long-range hydrodynamic effect due to a single vesicle in linear flow
Eldad Afik, Antonio Lamura, Victor Steinberg
Vesicles are involved in a vast variety of transport processes in living organisms. Additionally, they serve as a model for the dynamics of cell suspensions. Predicting the rheolog…
Oscillatory elastic instabilities in an extensional viscoelastic flow
Atul Varshney, Eldad Afik, Yoav Kaplan +1
Dilute polymer solutions are known to exhibit purely elastic instabilities even when the fluid inertia is negligible. Here we report the quantitative evidence of two consecutive os…
Wrinkling instability of vesicles in steady linear flow
Michael Levant, David Abreu, Udo Seifert +1
We present experimental observations and numerical simulations of a wrinkling instability that occurs at sufficiently high strain rates in the trembling regime of vesicle dynamics…
Fluid Vesicles in Flow
David Abreu, Michael Levant, Victor Steinberg +1
We review the dynamical behavior of giant fluid vesicles in various types of external hydrodynamic flow. The interplay between stresses arising from membrane elasticity, hydrodynam…
Characteristic spatial scale of vesicle pair interactions in a plane linear flow
Michael Levant, Julien Deschamps, Eldad Afik +1
We report the experimental studies on interaction of two vesicles trapped in a microfluidic analog of four-roll mill, where a plane linear flow is realized. We found that the dynam…
