A time-gated ballistic imaging instrument is used to obtain high-spatial-resolution, single-shot images of the liquid core in a water spray issuing into a gaseous crossflow. We describe further development of the diagnostic technique to improve spatial resolution and present images and statistics for various jets under crossflow experimental conditions (different Weber numbers). Series of these images reveal a near-nozzle flow field undergoing breakup and subsequent droplet formation by stripping. One can also detect signatures of spatially periodic behavior in the liquid core and formation of small voids during breakup.
一种时间选通弹道成像仪器用于获取向气体横流中喷射的水雾中液芯的高空间分辨率单次图像。我们描述了诊断技术的进一步发展以提高空间分辨率，并展示了在横流实验条件（不同韦伯数）下各种射流的图像和统计数据。这些图像系列揭示了近喷嘴流场经历破碎并随后通过剥离形成液滴的过程。人们还可以检测到液芯中空间周期性行为的特征以及破碎过程中小空隙的形成。
