N2 - When a liquid at a high pressure is driven out through an orifice to below its saturation pressure, flash-boiling of the homogeneous nucleation type may occur such that it results in high quality liquid atomization. This is one of the most effective means of generating a fine and narrow droplet size dispersed spray. The occurrence of flash boiling atomization involves kinetic stability problems and is subjected to two criteria which include a sufficient initial liquid temperature and a sufficient pressure drop rate. In this work, we analyze these criteria, and suggest a logically based explanation for the first (temperature) criterion.
