Insulated multinozzle system for electrohydrodynamic atomization in the simple-jet mode

Abstract

In this study, a multinozzle electrohydrodynamic atomization device was designed and studied for electrosprays in the simple-jet mode. Results have shown that the proposed device produces droplets with similar diameter in all nozzles, that the electric field creates a unique dispersion of the charged droplets and that it can operate under relatively high humidity conditions.

Investigation on cone jetting regimes of liquid droplets subjected to pyroelectric fields induced by laser blasts

“…These include some early works from Basaran's group, [17][18][19][20] and from Hayati et al who studied the mechanism of EHD spraying. 21 More recent works deal with other specific topics such as the effects of bulk charges and relaxation time on arc electrospraying, 22 the scaling laws for the disintegration of electrified drops, 23 the characterization and optimization of experimental parameters in jetting performance, [24][25][26][27] the oscillations of water droplets on insulating surfaces, 28 the EHD response of low-conductivity pendant drops to a step change in the electric field, 29 the liquid meniscus oscillations and tip streaming under continuous and pulsed voltages, [30][31][32] the development of a multi-nozzle EHD device, 33 the investigation on the regimes of water-oil interface, 34 numerical simulation of cone-jet formation in electrostatic spray, 35 and the stability of liquid bridges between two opposite Taylor cones. 36 However, the most studied configuration is that used in EHD inkjet devices where an electric field is established between a source nozzle and an extractor electrode.…”
