Piercing A Liquid Droplet By A Gas Jet

Impingement of a gas jet on a suspended water droplet is studied experimentally. The jet penetration process depends on the jet velocity and jet to droplet diameter ratio. At small jet to diameter ratios and large enough jet velocities, the jet penetrated through the droplet. At larger jet to droplet diameter, the droplet fragmentation becomes more significant, with large droplet deformation. For this experiment, different types of breakup process are categorized, and theoretical explanations are provided.
