Standardizing Spray Droplet Size Distributions

2022
An increasing number of companies and institutions have facilities that allow for the evaluation of droplet size associated with spray application from agrochemical nozzles. In response to the newly launched Council of Producers and Distributors of Agrotechnology (CPDA) Application Enhancement Program (AEP), there is an immediate need for a tool that ...

Prediction of the droplet size distribution in aerodynamic droplet breakup

Journal of Fluid Mechanics, 2022
The rim and bag dynamics in aerodynamic droplet breakup are investigated experimentally and theoretically. Three main modes contribute to the breakup sizes in aerodynamic droplet breakup: the rim node, the remaining rim and the bag breakup modes. However, existing models only consider one mode and are, therefore, unable to predict the size distribution.

Droplet size distributions in cryogenic flash atomization

International Journal of Multiphase Flow, 2021
Abstract Flash atomization can occur in rocket thrusters operated at near vaccum conditions just prior to ignition when cryogenic propellants are injected into the reaction chamber. Although the morphology of flashing sprays has been widely studied, empirical observations of the primary breakup mechanisms at the micro-scale are currently not feasible.

Droplet size distribution and ice shapes

36th AIAA Aerospace Sciences Meeting and Exhibit, 1998
Since aircraft operate in freezing rain (ZR) and freezing drizzle (ZL) during the winter months, it is important that we recognize the supercooled large droplet (SLD)1 environment and analyze its impact on aircraft operation and performance. ZR and ZL are subsets of SLD conditions.

Sizes distributions of large He droplets

Chemical Physics Letters, 2014
Abstract The size distribution and droplet flux in a beam of large He droplets of about 1010 atoms were measured. Single droplets in the beam were isolated and subjected to multiple ionization events in the electron beam ionization region resulting in a burst of ejected He2+ ions which was analyzed via quadrupole mass spectrometry.

Size from Specular Highlights for Analyzing Droplet Size Distributions

2009
In mechanical engineering, heat-transfer models by dropwise condensation are under development. The condensation process is captured by taking many pictures, which show the formation of droplets, of which the size distribution and area coverage are of interest for model improvement.

Optical Heterodyne Measurement of Cloud Droplet Size Distributions

Applied Optics, 1973
Optical heterodyne spectra of laser light quasi-elastically scattered by falling water droplets (1-10-micro radius) in a diffusion cloud chamber were used to determine the droplet size distribution. The rate of fall depends on radius in a known way, thus yielding a heterodyne spectrum manifesting a distribution of Doppler shifts.
