Size-Dependent and Property-Independent Passive Microdroplet Sorting by Droplet Transfer on Dot Rails

open access: yesMicromachines, 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

Equivalence of Two Different Integral Representations of Droplet Distribution Moments in Condensing Flow [PDF]

open access: yes, 2004
It is proved that two different and independently derived integral representations of droplet size distribution moments encountered in the literature are equivalent and, moreover, consistent with the general dynamic equation that governs the droplet size

Continuous Growth of Droplet Size Variance due to Condensation in Turbulent Clouds [PDF]

open access: yes, 2015
We use a stochastic model and direct numerical simulation to study the impact of turbulence on cloud droplet growth by condensation. We show that the variance of the droplet size distribution increases in time as t^{1/2}, with growth rate proportional to

Measurement of Sprinkler Droplet Size [PDF]

open access: yesApplied 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.

Droplet size distribution in homogeneous isotropic turbulence [PDF]

open access: yes, 2011
We study the physics of droplet breakup in a statistically stationary homogeneous and isotropic turbulent flow by means of high resolution numerical investigations based on the multicomponent lattice Boltzmann method.

Simulation and Experiment on Droplet Volume for the Needle-Type Piezoelectric Jetting Dispenser

open access: yesMicromachines, 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

open access: yesPhysical 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

Thermoresponsive Effects in Droplet Size Distribution, Chemical Composition, and Antibacterial Effectivity in a Palmarosa (Cymbopogon martini) O/W Nanoemulsion

open access: yesColloids and Interfaces
The 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

Effect of process parameters on emulsion stability and droplet size of pomegranate oil-in-water

open access: yesGrasas 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.
