title: Visualization of acceleration in multiphase fluid interactions.
abstract: Probing the dynamics of structures in turbid media is important for understanding the internal forces that 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 time-gated 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 time-resolved velocity and acceleration vectors representing motion and forces involved in spray development.
