The rising velocity of an isolated bubble in a "two-dimensional" air-fluidised bed has been measured and found to be wel1 described by the relation, ub= 15'9Abf cm/sec, where Ab is the area of the bubble measured in cm\*. This predicts a smaller rising velocity than the corresponding @avies and Tayl
Based on the observed pattern of coalescence of bubble pairs in vertical alignment in a two-dimensional bed, a theory is developed which describes how bubble size and frequency changes with height in a gas fluidised bed. It is confirmed by comparison with the reported data from 10 separate investiga
