Polymers in turbulence: stretching statistics and the role of extreme strain-rate fluctuations
Jason R. Picardo, Emmanuel L. C. VI M. Plan, Dario Vincenzi
Polymers in a turbulent flow are stretched out by the fluctuating velocity gradient; the stationary probability distribution function (p.d.f.) of extensions has a power-law tai…
Spirographic motion in a vortex
Sumithra Reddy Yerasi, Rama Govindarajan, Dario Vincenzi
Studies of particle motion in vortical flows have mainly focused on point-like particles, either inertial or self-propelled. This approximation assumes that the velocity field that…
How to extract a spectrum from hydrodynamic equations
John D. Gibbon, Dario Vincenzi
Practical results gained from statistical theories of turbulence usually appear in the form of an inertial range energy spectrum and a cut-off wave-numb…
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…
Effect of internal friction on the coil-stretch transition in turbulent flows
Dario Vincenzi
A polymer in a turbulent flow undergoes the coil-stretch transition when the Weissenberg number, i.e. the product of the Lyapunov exponent of the flow and the relaxation time of th…
How close are shell models to the 3D Navier-Stokes equations?
Dario Vincenzi, John D. Gibbon
Shell models have found wide application in the study of hydrodynamic turbulence because they are easily solved numerically even at very large Reynolds numbers. Although bereft of…
