Abstract

The dependence of dripping dynamics from physical properties of the nozzles is investigated. The analysis is performed by means of two complementary methods: (i) long dripping time series recorded with a standard laser-beam apparatus; and (ii) drop formations observed with a fast digital camcorder. Dripping from nozzles of different sizes is analyzed, and the formation of satellite drops is related to the preeminent physical parameter of control (flow rate). Quasielastic collisions between parent and satellite drops are observed.
