Effect of Forced Oscillations on Stream Decay (Vliyaniye Vynuzhdennykh Kolebaniy Na Raspad Strui)

Abstract

The effect of vibrations on the disintegration of a liquid jet was studied theoretically and experimentally. Equations were derived for the variations in a jet radius in the presence of vibrations. The experimental study was made in an assembly containing a glass nozzle 0.5 to 1.2 mm in diameter which was placed in a plastic tube mounted in a holder connected to a mechanical vibrator (up to 10,000 cps). The disintegration of the horizontal water jets was recorded photographically. When the vibrations were in resonance with the natural frequency of the jet, the non-disintegrated section of the jet was shortened by a factor of 2.5. Forced vibrations with frequencies differing from the natural frequency or its multiples had little effect on jet disintegration. It is concluded that forced nozzle vibrations with resonance frequencies can be used to intensify atomization processes.
