Characterization of Primary Atomization Processes of Like-on-Unlike Impinging Injectors
摘要
The present work investigates the primary atomization characteristics of like-on-unlike impinging injectors. Planar laser-induced fluorescence imaging experiments are conducted in both front and side view configurations to capture the sheet breakup processes. Four different breakup regimes are identified for a Weber number range of 187–2994. It is observed that the propagation of impact waves dictates the sheet breakup process and successive ligament formation, in higher Weber number cases. Different linear sheet parameters such as sheet breakup length, sheet width, and sheet thickness are quantified at low Weber number conditions.
