Superheated Water Atomization: A Possibility of Obtaining Sprays of Droplets of Micron Diameters

In the given brief communication, new experimental data on superheated water atomization are presented. It is shown that in contrast to the case of short cylindrical nozzles, which provide bimodal water–droplet sprays, the application of divergent nozzles makes it possible to obtain one-modal water atomization with droplets of about micrometer diameter. This is explained by the changes in the mechanism of superheated water jet fragmentation.
