Avalanche Size and Interevent Time Statistics in Amorphous System
Thomas Muhren, Roberto Benzi, Mauro Sbragaglia +2
The intermittent, stick-slip flow of amorphous systems is characterized by avalanches whose statistical properties display robust power-laws. In this paper, we study avalanche stat…
The Allee Effect in Compressible Flows
Jonathan Bauermann, Roberto Benzi, David R. Nelson +1
Microbes in marine environments are often confined to thin near-surface layers while being advected by turbulent flows. Because such constrained advection generates an effectively…
Stochastic resonance of rotating particles in turbulence
Ziqi Wang, Xander M. de Wit, Roberto Benzi +4
The chaotic dynamics of small-scale vorticity plays a key role in understanding and controlling turbulence, with direct implications for energy transfer, mixing, and coherent struc…
Ductile-to-brittle transition and yielding in soft amorphous materials: perspectives and open questions
Thibaut Divoux, Elisabeth Agoritsas, Stefano Aime +37
Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays and cementitious pastes to emulsions and physical gels encountered in food or biomedical e…
Additive Equivalence in Turbulent Drag Reduction by Flexible and Rodlike Polymers
Roberto Benzi, Emily S. C. Ching, T. S. Lo +2
We address the "Additive Equivalence" discovered by Virk and coworkers: drag reduction affected by flexible and rigid rodlike polymers added to turbulent wall-bounded flows is limi…
Maximum Drag Reduction Asymptotes and the Cross-Over to the Newtonian Plug
R. Benzi, E. De Angelis, I. Procaccia +2
We employ the full FENE-P model of hydrodynamics of a dilute polymer solutions to derive a theoretical approach to drag reduction in wall bounded turbulence. We recapture the resul…
