In this paper, a novel mechanism allowing greater control over the formation of droplets is
presented. This is achieved via the use of a dynamic nozzle of adjustable diameter.
It is demonstrated that, by using such a nozzle, it is possible to greatly modify the
and breakup of the ligament behind the main drop, leading to an overall reduction in
the number of satellite droplets. Furthermore, by adjusting the delay between
the beginning of the forming of the drop and the start of the nozzle constriction, a
greater control over both the number of satellites and the size of the main drop can be
achieved. It is also shown that only a minimal reduction of the nozzle’s effective
diameter is required in order to exploit the positive effects of the technique
presented here. This opens the possibility of incorporating the technique into
current droplet generator systems, e.g., via the use of piezoelectric
driven nozzles or other micro-mechanical actuation technology.
