Abstract

Shows by means of high-speed motion pictures that the breakup of a jet passes successively through three phases (breakup according to Rayleigh — breakup according to Weber-Haenlein — atomization), and that the transition from one phase to the next occurs at increasing higher Reynolds No's. as a function of a dimensionless term, containing viscosity, surface tension, density, and orifice diameter Z = η / √(σ ρ d) where η is the absolute viscosity, σ is the surface tension, ρ is the density and d is the orifice diameter.
