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

Droplet deformation and heat transfer in isotropic turbulence

Journal of Fluid Mechanics, 2017
The heat and mass transfer of deformable droplets in turbulent flows is crucial to a wide range of applications, such as cloud dynamics and internal combustion engines. This study investigates a single droplet undergoing phase change in isotropic turbulence using numerical simulations with a hybrid lattice Boltzmann scheme.

Heat transfer of a spray droplet in a PWR pressurizer

KSME Journal, 1991
Heat transfer rates to spray droplets under conditions corresponding to those of spray transients in a pressurizer of pressurized water reactor (PWR) have been predicted by a simple droplet model with internal thermal resistance and partial internal mixing.

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.

Transfer of heterogeneous droplets in the field of a temperature gradient

Journal of Engineering Physics and Thermophysics, 1993
The thermophoresis of a double-layer moderately large volatile droplet with a solid core, placed in a binary viscous gas mixture, is considered The thermodiffusion within the volume of a two-component gas mixture is allowed for, and all corrections for the Knudsen number are taken into, account completely.

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.
