Abstract: A previously unreported feature of the coalescence of water drops was observed for an isolated pair of drops (R = 275 ?m and r = 200 ?m) falling at terminal velocity through nearly saturated air. This new feature, grazing ...

Abstract: Observations of the effects of relative humidity on coalescence are limited to studies using supported drops or streams of drops, and the results are contradictory. In this paper, findings are presented on the effect of ...

Abstract: Self-collection efficiencies were measured for isolated drop pairs failing at terminal velocity using orthogonal cameras to obtain the horizontal offset of the drops before collision and the collision outcome. Data were ...
