Aerodynamic Droplet Breakup.
Abstract
A three-phase experimental investigation of the physical characterization of liquid droplet behavior within the nozzle contraction were described. These processes are inherentlly dependent. Initial deformations which result in increased accelerations and decreased slip velocity affect the droplet condition at the point of fragmentation. In the initial experiment, conventional liquids were used to study the effects of two liquid properties, namely surface tension and viscosity. Holographic observation of the droplet acceleration, deformation and fragmentation processes within the nozzle contraction were recorded. Holographic observations revealed the dramatic increase in droplet acceleration caused by the initial deformation. Later observations revealed classical breakup mechanisms and finally the fragment size distribution was determined.
