Water Structure at the Hydrophobic Droplet Surface Revealed by Vibrational Sum Frequency Scattering using Isotopic Dilution [PDF]
, 2022 Water structure at the hydrophobic/water interface is key towards understanding hydrophobicity at the molecular level. Herein, we characterize the hydrogen bonding network of interfacial water next to sub-micron sized hydrophobic droplets dispersed in ...

On the dispersion of a developing droplet spectrum in a turbulent cloud
Tellus, 1974 It is shown that the combined effects of condensation and shear-induced coalescence are able to produce significant dispersion in an initially narrow droplet spectral density centred on a radius of about 10 ?m. Provided that the degree of supersaturation of the ambient air is sufficiently large, the time scale for this dispersion process is small ...

Modeling Droplet Breakage in Continuous Emulsification Using Static Mixers in the Framework of the Entire Spectrum of Turbulent Energy [PDF]
, 2021 Droplet breakage during continuous emulsification in static mixers is investigated in this work. It is clearly shown that for viscous continuous phases, droplet breakage occurs mostly in the dissipation range of isotropic turbulence.

Electrostatic Effects of Corona Discharge on the Spectrum and Density Evolution of Water Droplets in Air [PDF]
IEEE Access, 2020 As one of the emerging application areas of the corona discharge technique, rain enhancement induced by atmospheric air ionization has made a great breakthrough. Although natural rainfall modified by artificial ionization was successfully observed via the statistical data of field experiments, deficient efforts have been devoted to the research on the ...

SPECTRUM AND VELOCITY OF DROPLETS OF SPRAY NOZZLES WITH AND WITHOUT AIR INDUCTION [PDF]
Engenharia Agrícola, 2018 ABSTRACT The aim of this study was to evaluate the spectrum and the velocity of droplets produced by nozzles with and without air induction, under different pressures and flow rates. The experiment was conducted in a completely randomized design with five replications, in a factorial 2 x 3 x 3 (two spray nozzles, three flow rates and three operating ...
