Cluster Dynamics of Planetary Waves
Elena Kartashova, Victor S. L'vov
The dynamics of nonlinear atmospheric planetary waves is determined by a small number of independent wave clusters consisting of a few connected resonant triads. We classified the…
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…
Drag Reduction by Polymers in Wall Bounded Turbulence
Victor S. L'vov, Anna Pomyalov, Itamar Procaccia +1
We address the mechanism of drag reduction by polymers in turbulent wall bounded flows. On the basis of the equations of fluid mechanics we present a quantitative derivation of the…
Multi-Zone Shell Model for Turbulent Wall Bounded Flows
Victor S. L'vov, Anna Pomyalov, Vasil Tiberkevich
We suggested a \emph{Multi-Zone Shell} (MZS) model for wall-bounded flows accounting for the space inhomogeneity in a "piecewise approximation", in which cross-section area of the…
Clustering of inertial particles in a turbulent flow
Tov Elperin, Nathan Kleeorin, Michael A. Liberman +3
We analyzed formation of small-scale inhomogeneities of particle spatial distribution (particle clustering) in a turbulent flow. The particle clustering is a consequence of a spont…
One-fluid description of turbulently flowing suspension
Victor S. L'vov, Anna Pomyalov
We suggested a one-fluid model of a turbulent dilute suspension which accounts for the ``two-way'' fluid-particle interactions by -dependent effective density of suspension and…
