Abstract: Experiments with charged water droplets show the existence of the metastable states predicted by Cahn as well as the well-known unstable state predicted by Lord Rayleigh. The charge lost at metastability is completely ...

Abstract: Collision efficiencies E have been determined from particle trajectories for the case of a 1-mm glass sphere and 6?20 ? spherical glass particles falling in still air. An empirical formula for the dependence of E upon ...

Abstract: The collision of a falling drop With a small particle has been studied by high-speed photography. The trajectory of the particle relative to the center of the drop and relative to a fixed point has been determined under ...
