✦ Synopsis

An improved electroresistivity probe has been used in a freely bubbling gas-fluidised bed of carbon particles to give the distributions of velocitj and size of bubbles therein. Bubble properties agree with previous observations but the significant influence of macro-circulation patterns on bubble velocities has been revealed.

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\*.

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
