Navier-Stokes hydrodynamics of thermal collapse in a freely cooling granular gas
Itamar Kolvin, Eli Livne, Baruch Meerson
We employ Navier-Stokes granular hydrodynamics to investigate the long-time behavior of clustering instability in a freely cooling dilute granular gas in two dimensions. We find th…
The Knudsen temperature jump and the Navier-Stokes hydrodynamics of granular gases driven by thermal walls
Evgeniy Khain, Baruch Meerson, Pavel V. Sasorov
Thermal wall is a convenient idealization of a rapidly vibrating plate used for vibrofluidization of granular materials. The objective of this work is to incorporate the Knudsen te…
Attempted density blowup in a freely cooling dilute granular gas: hydrodynamics versus molecular dynamics
Andrea Puglisi, Michael Assaf, Itzhak Fouxon +1
It has been recently shown (Fouxon et al. 2007) that, in the framework of ideal granular hydrodynamics (IGHD), an initially smooth hydrodynamic flow of a granular gas can produce a…
A nonlinear theory of non-stationary low Mach number channel flows of freely cooling nearly elastic granular gases
Baruch Meerson, Itzhak Fouxon, Arkady Vilenkin
We use hydrodynamics to investigate non-stationary channel flows of freely cooling dilute granular gases. We focus on the regime where the sound travel time through the channel is…
Formation of density singularities in ideal hydrodynamics of freely cooling inelastic gases: a family of exact solutions
Itzhak Fouxon, Baruch Meerson, Michael Assaf +1
We employ granular hydrodynamics to investigate a paradigmatic problem of clustering of particles in a freely cooling dilute granular gas. We consider large-scale hydrodynamic moti…

We show that the van der Waals-like phase separation instability of a driven granular gas at zero gravity, previously investigated in two-dimensional settings, persists in three di…
Phase separation of a driven granular gas in annular geometry
Manuel Diez-Minguito, Baruch Meerson
This work investigates phase separation of a monodisperse gas of inelastically colliding hard disks confined in a two-dimensional annulus, the inner circle of which represents a "t…
Formation and evolution of density singularities in hydrodynamics of inelastic gases
Itzhak Fouxon, Baruch Meerson, Michael Assaf +1
We use ideal hydrodynamics to investigate clustering in a gas of inelastically colliding spheres. The hydrodynamic equations exhibit a new type of finite-time density blowup, where…
Thermal collapse of a granular gas under gravity
Dmitri Volfson, Baruch Meerson, Lev S. Tsimring
Free cooling of a gas of inelastically colliding hard spheres represents a central paradigm of kinetic theory of granular gases. At zero gravity the temperature of a freely cooling…
Shear-induced crystallization of a dense rapid granular flow: hydrodynamics beyond the melting point?
Evgeniy Khain, Baruch Meerson
We investigate shear-induced crystallization in a very dense flow of mono-disperse inelastic hard spheres. We consider a steady plane Couette flow under constant pressure and negle…
Far-from-equilibrium Ostwald ripening in electrostatically driven granular powders
M. V. Sapozhnikov, A. Peleg, B. Meerson +2
We report the first experimental study of cluster size distributions in electrostatically driven granular submonolayers. The cluster size distribution in this far-from-equilibrium…

Evgeniy Khain, Baruch Meerson, Pavel V. Sasorov
Equations of granular hydrostatics are used to compute the phase diagram of the recently discovered van der Waals-like phase separation in a driven granular gas. The model two-dime…
Oscillatory instability in a driven granular gas

We discovered an oscillatory instability in a system of inelastically colliding hard spheres, driven by two opposite "thermal" walls at zero gravity. The instability, predicted by…
Close-packed floating clusters: granular hydrodynamics beyond the freezing point?

Granular materials fluidized by a rapidly vibrating bottom plate often develop a fascinating density inversion: a heavier layer of granulate supported by a lower-density region. We…
