Abstract
Observations of inception and desinent cavitation numbers in small submerged jets, and observations of the flashing of small, highly superheated, free jets, are presented. The observations, made over a range of jet sizes and water temperatures, reveal a strong influence of geometric scale in both systems. The water temperature has little effect upon the cavitation number for the submerged jet except at high temperatures. Flashing occurs in the free jet after a delay time which is shown to vary as the (−7/2) power of the liquid superheat, and inversely as the jet area.
