An Acceleration System for Water Drops

Abstract

Linear accelerator systems are described which allow the production of series of homogeneously sized water drops of different diameter and at terminal velocity, with small oscillations, negligible charges, and in air of low turbulence intensity. Combinations of parallel systems and blowers displacing the smaller drops into the path of the larger ones allow the study of collision and breakup under conditions which essentially duplicate nature. The chances to observe interactions are considerably enhanced by opto-electronic selection devices.
