Electrospray is the atomization of liquid caused by an applied electric field. Much research has been done based on dc electrical excitation of liquid transported to a nozzle under constant flow conditions. In contrast, very little research has been conducted in the area of pulsed electrospray, i.e. atomization based on time-varying electrostatic excitation. We report for the first time that his technique is capable of 1) spray-on-demand for a range of volume flow rates, pulse heights, pulse widths, pulse train frequencies and 2) continuous spray with higher energy efficiency compared to dc excitation in terms of flow rate per watt of electrical power.
