Vertically shaken column of spheres. Onset of fluidization

The onset of surface fluidization of granular material in a vertically vibrated container, z = A cos (ωt), is studied experimentally. Recently, for a column of spheres it has been theoretically found [1] that the particles lose contact if a certain condition for the acceleration amplitude z̈ ≡ Aω/g = f(ω) holds. This result is in disagreement with other findings where the criterion z̈ = z̈crit = c...

Phase Diagram of Vertically Shaken Granular Matter

A shallow, vertically shaken granular bed in a quasi 2-D container is studied experimentally yielding a wider variety of phenomena than in any previous study: (1) bouncing bed, (2) undulations, (3) granular Leidenfrost effect, (4) convection rolls, and (5) granular gas. These phenomena and the transitions between them are characterized by dimensionless control parameters and combined in a full ...

Fluidization of 1204 spheres: simulation and experiment

In this paper we study the fluidization of 1204 spheres at Reynolds numbers in the thousands using the method of distributed Lagrange multipliers. The results of the simulation are compared with a real experiment. This is the first direct numerical simulation of a real fluidized bed at the finite Reynolds number encountered in the applications. The simulations are processed like real experiment...

Direct Numerical Simulation of Fluidization of 1204 Spheres

One goal pursued there is to demonstrate that numerical experiments on fluidization can be processed in log-log plots for straight lines leading to power laws as did Richardson and Zaki 1954 for real experiments. As far as we know, we are the only group of researchers to carry out this program. There is no prior literature, in which power laws are obtained from numerical experiments. On the oth...

Propagation of Elastic Waves in Deep Vertically Shaken Particle Beds.

A wave traveling upward through a particle bed is observed to steepen and form a shock as the surface is approached. This steepening is due to the increase in the local speed of sound that is induced by the local pressure increase in the upward moving phase of the wave behind the wave front. The pressure increase leads to an increase in the local coordination number which in turn increases the ...
