Abstract

Dynamics of a single vapor cavity, moving under gravity in a vertical tube of a small diameter, has been studied. The experiment was carried out in water and aqueous LiBr solution in a tube with the length of 400 mm and diameter of 16 mm. Experiments have shown that dynamics of the rising vapor cavity after-the-fact boiling-up of aqueous LiBr solution in a vertical tube of a small diameter for some initial conditions differs qualitatively from dynamics of a gas bubble rising in a pool. Dynamics of the vapor cavity in aqueous LiBr solution and in water demonstrates quantitative but not qualitative differences. During bubble rising in a small diameter tube to time dependence for volume and mass of the vapor bubble, the regimes with pulsations were detected.
