Photographic Study of Breakup of Liquid Drops

A high-speed photographic study was made to investigate the mechanisms of aerodynamic breakup of liquid drops in the flow behind a plane shockwave. The desired flow conditions were generated in a small shock tube instrumented to measure parameters necessary to determine existing flow conditions and to provide for synchronization of the high-speed events with the photographic equipment. High-speed motion pictures, taken at the rate of 26,000 frames/s were made of the deformation and subsequent breakup of free-falling liquid drops in the flow behind the shockwave. The parameters which were varied during the study included the flow velocity, droplet size, and the surface tension, viscosity and density of the liquid. The operation of the experimental equipment is described and results obtained from the study are presented and discussed.
