Abstract

The breakup of a jet consisting of two coaxial jets of immiscible liquids has been studied experimental with varying phase flow rates. Distilled water and a mixture of polymethylsiloxanes were used as working liquids. Jet breakup regimes, the types of capsules formed, and the sizes of single-core capsules formed under the influence of capillary instability were determined. The natural frequencies of surface instability were measured.

两相同轴微射流的流动和破裂实验研究

摘要在实验中研究了由两股同轴不相溶液体射流组成的射流在不同相流速下的破裂情况。蒸馏水和聚甲基硅氧烷混合物被用作工作液体。研究确定了毛细管不稳定性影响下的喷射破裂机制、形成的胶囊类型以及单核胶囊的尺寸。测量了表面不稳定性的固有频率。
