Abstract

Capillary oscillations on perturbed liquid jets have been investigated using laser illumination and improved electronic detection of the magnified jet shadow. The amplitudes and phase shifts of several wave harmonics of a growing spatial instability were measured as a function of distance from the orifice for a range of initial disturbance amplitudes. The measurement of the jet diameter and its derivative, could be used to calculate the transient elongational viscosity of highly dilute polymer liquids. The elongational viscosity has recently been established as a controlling parameter in the atomization of non-Newtonian fluids.
