Summary
The internal-gelation process can be used to permanently immobilize highly radioactive nuclear wastes. A study was conducted to determine the factors affecting the formation of stable, uniform droplets from a vibrating nozzle, which is a critical step in this process. Experimental data were collected using four nozzle diameters (325 to 586 ..mu..m) with jet velocities ranging from 1 to 10 m/s, and three test liquids, whose physical properties cover the possible range of the waste fluid. A dimensional analysis identified the pertinent dimensionless groups as Reynolds, Weber, Froude, and Power numbers, and a dimensionless droplet spacing. Power-function correlations of the data in these dimensionless groups are presented, which define the region of good droplet formation. A unique catcher-stream design is also presented, which improves performance of the process at higher flow rates and frequencies.
