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
Experiments were conducted to study the solids holdup in the near wake behind a single bubble in a two-dimensional liquid-solid fluid&d bed. An optical fiber probe system was developed for the measurement of local solids holdup. Based on the local solids holdup distribution in the bubble wake, the p
