Re-laminarization of elastic turbulence
M. Vijay Kumar, Atul Varshney, Dongyang Li +1
We report frictional drag reduction and a complete flow re-laminarization of elastic turbulence (ET) at vanishing inertia in a viscoelastic channel flow past an obstacle. We show t…
Elastic instability in a straight channel of viscoelastic flow without prearranged perturbations
Yuke Li, Victor Steinberg
We report experimental results on elastic instability in a viscoelastic channel shear flow due to only a natural non-smoothed inlet and small holes along the channel for pressure m…
Splitting of localized disturbances in viscoelastic channel flow
Ron Shnapp, Victor Steinberg
We examine the response of an inertia-less viscoelastic channel flow to localized perturbations. A simplified model shows that the non-linear interaction between the velocity and e…
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…
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…
Non-modal elastic instability and elastic waves in weakly perturbed channel flow
Ron Shnapp, Victor Steinberg
In this paper, we present experimental results and reveal that strong perturbations are not necessary for elastic instability to occur in straight-channel, inertialess, visco-elast…
