Effect of Nozzle Geometry on Particle Size Distribution in Atomized Spray of Metastable Superheated Liquid

Abstract

It is experimentally shown that diverging nozzles with a cone angle of 12o -14° and a length of 10-15 mm provide the finest atomization of metastable superheated liquid with a submicron droplet fraction at a level of 65-70%.
