Water droplet deformation under the motion in gas area with subsonic velocities

Abstract

The experimental investigation of water droplet deformation (characteristic dimensions 3 ÷ 6 mm) when moving through the gas area (air) with 1÷ 5 m/s velocities was carried out. The high-speed (delay time between the frames is less than 100 ns) tools of cross-correlation videorecording were used. A cyclic change nature of the droplet shapes (from close to spherical to conditionally ellipsoidal) was found. The characteristic times of "deformation cycles" and the maximal deviations of droplet dimensions relative to initial dimensions were determined. The influence of droplet velocities and its dimensions on the deformation characteristics was determined.
