摘要：

The atomization of metastable superheated water injected into the atmosphere through a convergent-divergent nozzle at a temperature of 240-260 & DEG;C was studied experimentally. The dispersion structure of the atomization plume is bimodal with a predominance of submicron droplets, whose proportion increases with increasing temperature and reaches 80% at the nozzle outlet at a water temperature of 260 & DEG;C. The influence of droplet coagulation on the distribution of the proportion of large droplets along the length of the atomization plume was estimated.
