Abstract
Supersaturation with gas is a useful complement to superheating or the application of tension to liquids for the study of bubble nucleation mechanisms, including that of ultrasonic cavitation. Although methods have been described for achieving very great supersaturation of gases in water, the size of the sample has always been small. In this paper a technique is described by which a large sample of water is aerated and then transferred under pressure to a hydraulic cell in which it is stabilized by the application of high hydrostatic pressure. In this way samples of up to a litre of stable supersaturated liquid can be obtained.
