摘要

A periodic excitation was applied to a compound liquid jet, which was composed of a core liquid, water, surrounded by a shell liquid, diesel oil, for an experimental investigation on its breakup. The core-to-shell mass ratio, γ, and the ratio of disturbance wavelength to undisturbed diameter of the compound jet, λ/D, were taken into consideration as parameters to describe the breakup processes of the compound jet. For γ < 0.36, the compound jet breakup was classified into six patterns. By comparing the breakup of a single diesel jet to that of a water-in-diesel compound jet, two conclusions were drawn. First, the uniform drop regime of the compound jet was wider than that of the single jet. Second, both the single jet and water-in-diesel compound jet broke randomly in the range of λ/D ≤ 3.
