The nonaxisymmetric (buckling) flow regime of fast capillary jets

This paper reports an experimental study of the nonaxisymmetric flow of a fast liquid jet discharging into the atmosphere. The nonaxisymmetric shape of the jet was photographed and subjected to a wavelength analysis. The results of the wavelength analysis demonstrate that the jet shape is governed by a narrow band of wavelengths associated with a characteristic value λ max which scales with the jet diameter D. It is shown that the experimental observations are in agreement with predictions based on hydrodynamic stability theory and buckling theory. © 1982 American Institute of Physics.
