Void Formation and Roughening in Slow Fracture
Itai Afek, Eran Bouchbinder, Eytan Katzav +2
Slow crack propagation in ductile, and in certain brittle materials, appears to take place via the nucleation of voids ahead of the crack tip due to plastic yields, followed by the…
Branching Instabilities in Rapid Fracture: Dynamics and Geometry
Eran Bouchbinder, Joachim Mathiesen, Itamar Procaccia
We propose a theoretical model for branching instabilities in 2-dimensional fracture, offering predictions for when crack branching occurs, how multiple cracks develop, and what is…
Drag Reduction by Microbubbles in Turbulent Flows: the Limit of Minute Bubbles
Victor S. L'vov, Anna Pomyalov, Itamar Procaccia +1
Drag reduction by microbubbles is a promising engineering method for improving ship performance. A fundamental theory of the phenomenon is lacking however, making actual design qui…
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…
The Polymer Stress Tensor in Turbulent Shear Flows
Victor S. L'vov, Anna Pomyalov, Itamar Procaccia +1
The interaction of polymers with turbulent shear flows is examined. We focus on the structure of the elastic stress tensor, which is proportional to the polymer conformation tensor…
Anisotropy in Turbulent Flows and in Turbulent Transport
Luca Biferale, Itamar Procaccia
We discuss the problem of anisotropy and intermittency in statistical theory of high Reynolds-number turbulence (and turbulent transport). We present a detailed description of the…
