Abstract

Probing the dynamics of structures in turbid media is important for understanding the internal forces which drive the time-evolution of many fluid systems; the breakup of fuel injection sprays is a prime example. We demonstrate a three-pulse configuration for timegated ballistic imaging, applied to a turbulent, steady spray allowing the acquisition of time-correlated image data. Coupled with targeted region-matching analysis, the detected image-triplets are used to generate timeresolved velocity and acceleration vectors representing motion and forces involved in spray development.
