Visualization of acceleration in multiphase fluid interactions
Journal article, 2016

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.
