Micromachines, 2018 A fully passive microdroplet sorting method is presented in this paper. On the rails with dot patterns, the droplets were sorted in different ways depending on their size. However, the effect of droplet properties on the threshold size of the sorting was

Atomized spray droplet size prediction from multi-hole nozzle for direct injection gasoline engines
Journal of Fluid Science and Technology, 2017 We investigated atomized spray droplet size from multi-hole nozzles for direct injection gasoline (DIG) engines. Our findings showed that the droplet size can be described by the nozzle-hole geometry. For the DIG engine, adequate spray pattern and finely

Simulation and Experiment on Droplet Volume for the Needle-Type Piezoelectric Jetting Dispenser
Micromachines, 2019 The needle-type piezoelectric jetting dispenser is widely applied in the microelectronics packaging field, and it is important to control the droplet size to ensure that the droplet jetting process is successful. In this study, we analyzed the influences

Vibration of submillimeter-size supported droplets
Physical Review E, 2006 We study the fundamental vibration mode of supported submillimeter-size droplets. Using an analogy with a simple oscillator we derive a semianalytical expression for the eigenfrequency and the scaling law of the energy dissipation within the droplet. The experimental results obtained for mercury drops deposited on glass are compared with the model. The

Measurement of Sprinkler Droplet Size [PDF]
Applied Engineering in Agriculture, 2001 Droplet distributions for rotating spray-plate sprinklers were measured using a laser technology and a flour methodology. In general, both methods produced comparable results. The flour method tended to produce d25, d50 and d75 values that were on the average about 0.20 mm (about 15% of the d 50 value) larger than laser values.

Colloids and InterfacesThe design of emulsions at the nanoscale is a significant application of nanotechnology. For spherical droplets and a given volume of dispersed phase, the nanometre size of droplets inversely increases the total area, A=3Vr, allowing greater contact with

The size and the duration of air-carriage of respiratory droplets and droplet-nuclei [PDF]
Epidemiology and Infection, 1946 1. The sizes of the droplets and droplet-nuclei produced by sneezing, by coughing and by speaking, were studied by the microscopic measurement of 12,000 droplet stain-marks found on slides exposed directly to mouth-spray, and of 21,000 stain-containing droplet-nuclei recovered from the air on to oiled slides exposed in the slit sampler.2.

Effect of process parameters on emulsion stability and droplet size of pomegranate oil-in-water
Grasas y Aceites, 2021 The development of efficient emulsion is essential and requires a good understanding of the parameters that govern the formation and stability of the emulsion. The droplet size significantly affects the stability of the emulsion.
