Introduction
摘要
In fluid mechanics, high-speed photographyHigh-speed photography is a technique for capturing the instantaneous interface dynamics (Versluis in Exp Fluids 54:1–35, 2013; Fuller in Imag Sci J 57:293–302, 2009; Field in Contemp Phys 24:439–459, 1983). By continuously capturing images within a short time, it enables the recording of momentary specifics during the motionMotion of the fluid interface. Based on this technology, one can obtain a complete physical process of the rapid motion.
