Exprimental Study of Liquid Drop Surface Transformation in Air Within a Group of Successive Deformation Cycles

Research output: Contribution to journalArticle


An experimental study has been made of transformation of surface of drops of liquids used widely in chemical engineering (water, kerosene, and ethyl alcohol) during their motion in air with moderate velocities (up to 5 m/sec). The initial sizes (nominal diameters) of the drops varied in the 3–6 mm range. The typical “cycles of deformation” of liquid drops with specific duration, length, and amplitudes of size variation have been established. More than 10 successive deformations during 1-m passage of liquid drops through the air are investigated. The typical time of transition from one drop shape to another is determined. Two deformation conditions differing in drop shapes and time of the respective transition are distinguished.
