    Breakup of a liquid jet
    (2019-10-20) Weber, Constantin
    The breakup phenomena (drop and wave formation) which can be observed at moderate velocities were investigated theoretically. Rotation-symmetric disturbances lead to drop formation. The breakup time is constant for every liquid and jet thickness at low velocities; the breakup length increases with the velocity. Wave formation is explained by the influence of aerodynamic forces and theoretical laws are derived which agree in character with the experiments.

    The formation of drops by nozzles and the breakup of liquid jets
    (2019-10-20) Ohnesorge, Wolfgang von
    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.
