Droplet size distribution and ice shapes
36th AIAA Aerospace Sciences Meeting and Exhibit, 1998Since 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.

Condensation Dynamics and Droplet Size Distribution
ASME 2017 15th International Conference on Nanochannels, Microchannels, and Minichannels, 2017Condensation phenomena are important for several engineering fields including HVAC, refrigeration, distillation/desalination of water, dehumidification, aerospace, and water harvesting applications. In this work, Microsphere Photolithography (MPL), a low-cost, bottom-up fabrication technique, was used for fabricating a silica nanopillar surface (0.7 μm

Droplet size distributions in cryogenic flash atomization
International Journal of Multiphase Flow, 2021Abstract 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.

Fluid bed agglomeration with a narrow droplet size distribution
International Journal of Pharmaceutics, 2000In the fluid bed agglomeration processes liquid distribution influences the agglomerate growth. We developed a new nozzle that produces uniform droplets, which allows droplets to be easily controlled in size independently of liquid- and airflow of the nozzle.

Droplet size distributions of nebulised aerosols for inhalation therapy
Clinical Physics and Physiological Measurement, 1986Jet nebulisers are used commonly for aerosol therapy in patients with asthma and bronchitis, but the manufacturers' information regarding aerosol droplet size is often inadequate. In this study, mass median diameter, geometric standard deviation and the percentage of the aerosol mass contained within 'respirable' (less than 5 micron diameter) droplets ...

Droplet-size distribution and stability of lipid injectable emulsions
American Journal of Health-System Pharmacy, 2009The droplet-size distribution (DSD) and stability of multiple lots of lipid injectable emulsions were studied.A total of 234 commercial batches of Intralipid (Fresenius Kabi, Uppsala, Sweden) were characterized, and the influence of the emulsions' oil content on samples packaged in single- and three-chamber bags was tested. Larger-sized lipid particles

Optical Heterodyne Measurement of Cloud Droplet Size Distributions
Applied Optics, 1973Optical 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.

Cloud Condensation Nucleus Size Distributions and Their Effects on Cloud Droplet Size Distributions
Journal of the Atmospheric Sciences, 1977Abstract Cloud droplet size distributions, calculated from cloud condensation nucleus (CCN) measurements made beneath non-raining, warm clouds in western and eastern Washington State, show reasonable agreement with droplet size distributions measured in the clouds.

Size Distribution of Tobacco Smoke Droplets by a Replica Method
Nature, 1960HITHERTO it appears that when size distributions of tobacco smoke droplets have been made by light or electron microscopy, the droplets have been caught on glass surfaces or one of the usual kinds of specimen support film, and upon deposition they have spread on the sampling surface (Fig. 1a and c). As a result, published size distributions obtained by

Evolution of droplet size distribution and composition in miniemulsions
Journal of Polymer Science Part A: Polymer Chemistry, 2014ABSTRACTA fundamental understanding of the formation, degradation and polymerization of miniemulsions has been hindered by difficulties in quantifying their monomer droplet size distribution (DSD). In this work, particle sizing techniques including capillary hydrodynamic fractionation, acoustic attenuation spectroscopy, surfactant titration, and ...
