Abstract
This paper presents the results of an experimental study of the breakup of a jet consisting of two coaxial jets of immiscible liquids with varying phase flow rates. Distilled water and a mixture of polymethylsiloxanes were used as working liquids. The regimes of jet breakup, the types of capsules formed, and the sizes of single-chamber capsules formed under the influence of capillary instability were determined. The natural frequencies of surface instability were measured.
