Join us as we explore an innovative method to measure the trajectory of droplets using advanced light scattering technology. In this video, we demonstrate how changing the angle of a flat fan nozzle affects the light scattering signature of droplets, allowing us to predict their path accurately. We discuss the experimental setup, including the use of lasers and measurement props, and share exciting results that show consistent signatures for droplets coming from different angles. This technique has been patented and shows great promise for applications involving droplet characterization. Stay tuned as we plan to extend this research to rotary atomizers!
