Paper Abstract

In the present study, phosphorescent imaging technique was developed to achieve simultaneous measurements of droplet size, speed and temperature of dispersed droplets in spray flow ejected from an air-blast nozzle. By using phosphorescent molecules as the tracers excited by an ultraviolet laser sheet for the quantitative flow measurements, the detected images of tagged phosphorescent molecules at two successive times determine the dynamic and thermodynamic behaviors of dispersed particles. A PTV based method was used to analyze the droplets size, trajectory and speed, and a lifetime based approach was used to measure the cross-correlated droplets temperature. The experimental results demonstrated phosphorescent imaging technique behaves the potential to widely used and well suited for spray measurement and droplet characterization.
