Preserved Fulltext
This paper describes a visual study of the circulation pattern of glass beads in two dimensional vibrating particle beds. Flow visualization was achieved by filling the vessel with layers of glass beads of alternately contrasting color. The visual study revealed that particles rise in the central region and travel down near the side walls, with two relatively static layers being formed near the top and bottom of the bed. In addition, the circulation velocity was observed to increase with increasing bed height.
