摘要：A new breakup regime of liquid drops, named the dual-bag breakup regime, in a continuous and uniform air jet flow is identified at We ranging from 28 to 41 at the present investigation. The dual-bag breakup regime is characterized by two successive bag breakup processes; the first one is suffered by the initial main drop, and the second one is suffered by the core drop produced in the first bag breakup process. Shadowgraph and high-speed cameras were used to record the temporal properties of liquid drops in the dual-bag breakup regime. Parameters including breakup time, drop deformation rate, and volume fraction of core drop, are measured and given as a function of Weber numbers in the dual-bag breakup regime.
