dc.description.abstractThe interest in studying droplet related phenomena has been increasing over the last decades.In the fluid dispensing equipment industry, a major problem is to minimize droplet diameter andto eject droplets in a controlled manner with a low-cost device. Taking all this into account, anew low-cost droplet stream generator was designed and fabricated. The material used to man-ufacture the stream droplet generator structure was a 3D printable material, namely PLA, thatminimizes the device cost. This structure has three separate components: piezoelectric lid, fluidchamber, and pinhole holder. The disruptive waves of the disturbance mechanism were applieddirectly to the fluid instead of being applied to the precision pinhole. The interchangeable noz-zle used was a round stainless-steel high precision optical pinhole with three different sizes:100μm,150μm, and200μm. Jet attribute properties (droplet diameter, droplet velocity, anddistance between droplets) were measured as the different conditions changed (piezoelectriccell frequency, outlet pressure, and fluid). The present work studied the spray characteristicsand different monodisperse regimes. A full characterisation of them is presented and discussedin detail.pt_PT
