Combined with the general two-stage, uniform atomization model outside the nozzle, a complete model system for the single uniform diameter prediction is formed. Furthermore, the random characteristics of the liquid sheet primary breakup are described with the Monte Carlo method, and an improved model is proposed here to predict the droplet size distribution for the Y-jet nozzle. To verify the model system, a laser-diff action size-distribution analyzer was applied, and several different Y-jet nozzles were tested. Very good agreement between the experimental results and the model predictions are obtained and presented in this article. %8 2004-10-01
