The stability of a large two-dimensional gas bubble rising in an inviscid liquid because of buoyancy is studied. The analysis leads to the determination of a critical vertex angle subtended by the bubble. Bubbles with smaller vertex angles are shown to be unstable. This critical angle compares favou
## Communications (b) high degree of supersaturation is required before condensation takes place. The analysis presented will not be applicable to group (a). Little information is available on systems contained in group (b). Work by FRIEDLANDER and LEVINE 161 using steam and glycerol have found th
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
