Abstract:

As a result of previous research, we felt that accurate droplet velocity measurements would help produce scaling laws and provide better interpretation of the holographic droplet images. Therefore, we proceeded with a series of velocimetry experiments designed to provide accurate droplet profile and trajectory data. After completing the velocimetry experiments with conventional liquids, we proceeded with the liquid metals experiments. The results of the velocimetry experiments are summarized. The experiments with liquid metals are described in detail. Keywords include Droplet breakup, Fragmentation Droplet dynamicsNozzles Scaling laws--Critical Weber number, Breakup time Fragment size and Liquid metals--Mercury and Aluminum.
