Abstract in another language

The fluidization of a monolayer of glass beads in a horizontally and vertically vibrated annular container is studied. At peak forcing accelerations between 1.1 and 1.5 g, a solidlike and a gaslike domain coexist. The solid fraction decreases with increasing acceleration and shows hysteresis. The sharp boundaries between the two regions travel around the channel faster than the particles are transported. Complementary to our experimental studies, a molecular dynamics simulation is used to extract local granular temperature and number density. It is found that the number density in the solid phase is several times that in the gas, while the temperature is orders of magnitude lower.
