Features of the Transformation of Small Water Droplets and Large Water Bombs in Free Fall

Abstract

This paper presents a series of experimental studies to determine the basic characteristics and features of the transformation of small water droplets (3-6 mm) and large water bombs (50-100 mm) in free fall. Investigations have been carried out using cameras "Phantom V411" and "Phantom Miro M310". Software "Tema Automotive" have been used for data processing from video recordings. The regulations of the surface transformations of small droplets and large water bombs have been established. The stages of transformation (disintegration) have been established for large water bombs. The mechanisms of deformation have been defined for small droplets. The characteristic times have been determined for the defined stages of transformation. The study demonstrates the influence of the initial size of droplets and water bombs on the times and velocities of considered processes.
