The Effects of Impurities and Solutes upon the Charge Transfer of Droplets

Environmental Letters, 1971
Abstract The rates of charge transfer of evaporating droplets of radius less than 5 microns have been measured by means of a Millikan Oil Drop apparatus. As the evaporation proceeds, droplets of pure liquids seem to retain their charge at a near constant level, but droplets of liquid dispersions containing some immiscible substances steadily loose ...

Spontaneous transfer of droplets across microfluidic laminar interfaces

Lab on a Chip, 2016
Passive transfer of droplets across the laminar interfaces of two immiscible fluids is successfully achieved by precise control of the interfacial energies in a three phase microfluidic system.

The influence of coalescence on droplet transfer in vertical annular flow

Chemical Engineering Science, 1996
In vertical annular flow, the motion of droplets in the gas core is dominated either by a diffusion mechanism, when the droplet size is small, or by inertial effects when droplets are large. These two mechanisms have to be considered when predicting deposition rates. Furthermore, since droplet-droplet interactions influence droplet motion, a deposition

An investigation of droplet oscillation during mass transfer II. A dynamical investigation of oscillating spherical droplets

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1958
Abstract The equations of motion for the oscillation of a liquid drop pendent in another liquid have been derived. The predicted frequencies of oscillation for a number of systems having different physical properties (e. g. viscosity, density, drop radius, etc.) were found to be in good agreement with experiment.

Radiative Transfer and Cloud Droplet Growth

Journal of the Atmospheric Sciences, 1979
Abstract Two papers, Roach (1976) and Barkstrom (1978), estimating the significance of radiative transfer on cloud (or fog) droplet growth have recently appeared. While their Principal conclusions are in broad quantitative agreement, it is worth commenting briefly on such differences of emphasis as do exist.

Study of droplet transfer mechanism in GMAW

2003
A theoretical and experimental approach to computing the droplet transfer frequency in gas metal arc welding is discussed. In this study, welding experiments using a 0.045" diameter, ER70S-6 manganese steel wire were conducted to examine the droplet transfer mechanism using high-speed photography. Changes in both energy and mass inputs to the electrode

Oxygen Transfer From Falling Water Droplets

Journal of the Sanitary Engineering Division, 1969
Overall oxygen transfer coefficients are obtained for deaerated water droplets falling freely through the atmosphere with and without 50 ppm. of a synthetic detergent. Drop distances ranged from 0 to 13 ft, and droplet surface areas varied from 0.47 to 0.55 cm\U2\N.
