Nonlinear hydrodynamic instability and turbulence in pulsatile flow
Duo Xu, Atul Varshney, Xingyu Ma +4
Pulsating flows through tubular geometries are laminar provided that velocities are moderate. This in particular is also believed to apply to cardiovascular flows where inertial fo…
Stokes flow analogous to viscous electron current in graphene
Jonathan Mayzel, Victor Steinberg, Atul Varshney
Electron transport in two-dimensional conducting materials such as graphene, with dominant electron-electron interaction, exhibits unusual vortex flow that leads to a nonlocal curr…
Elastic Alfven waves in elastic turbulence
Atul Varshney, Victor Steinberg
Speed of sound waves in gases and liquids is governed by medium compressibility. There exists another type of non-dispersive waves which speed depends on stress instead of medium e…
Mixing layer instability and vorticity amplification in a creeping viscoelastic flow
Atul Varshney, Victor Steinberg
We report quantitative evidence of mixing-layer elastic instability in a viscoelastic fluid flow between two widely spaced obstacles hindering a channel flow at and $Wi\gg…
Drag enhancement and drag reduction in viscoelastic flow
Atul Varshney, Victor Steinberg
Creeping flow of polymeric fluid without inertia exhibits elastic instabilities and elastic turbulence accompanied by drag enhancement due to elastic stress produced by flow-stretc…
Elastic wake instabilities in a creeping flow between two obstacles
Atul Varshney, Victor Steinberg
It is shown that a channel flow of a dilute polymer solution between two widely spaced cylinders hindering the flow is an important paradigm of an unbounded flow in the case in whi…
