✦ Synopsis

The breaking up of a liquid jet subject to small disturbances was studied experimentally and theoretically. A non-linear theory was used to calculate the profile of the waves on the surface of the jet at breakup, and also to predict the volume of the main and satellite drops.

It was found that the theoretical and experimental drop volumes were in good agreement. However, satellites were observed in all the experiments whereas the theory predicts that satellites should not form for dimensionless wavenumbers greater than 0.7.

In the experiments it was not possible to make the jets break up into single main drops of uniform size. The results suggest that it may be possible to produce uniformly sized drops if the main and satellite drops have the same volume.
