Transfer cells and lipid droplets of someValerianaceae

Plant Systematics and Evolution, 1990
Development, structure and the axial distribution of transfer cells and their lignification were investigated inValerianella locusta, Valeriana officinalis, andV. tuberosa (Valerianaceae). Fundamental new results are: (1) Transfer cells often contain numerous lipid droplets. Within the stem the distribution of cells containing lipid droplets correlates

Resistance to mass transfer inside droplets

AIChE Journal, 1964
AbstractAn experimental investigation of the effects of various physical properties on the dispersedphase mass transfer coefficient was carried out for both nonoscillating and oscillating liquid droplets falling in a single stream through stationary continuous liquid phases.

Heat Transfer Within Deforming Droplets

Design, Application, Performance and Emissions of Modern Internal Combustion Engine Systems and Components, 2002
The effect of droplet oscillation on internal heat transfer was investigated using a transient, three-dimensional Navier-Stokes solver for free-surface flows. The code solves conservation of momentum and energy on a three-dimensional deforming domain.

Electron Transfer as a Liquid Droplet Contacting a Polymer Surface

ACS Nano, 2020
It has been demonstrated that substantial electric power can be produced by a liquid-based triboelectric nanogenerator (TENG). However, the mechanisms regarding the electrification between a liquid and a solid surface remain to be extensively investigated.

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.

Fundamental limits of jumping droplet heat transfer

Applied Physics Letters, 2020
Liquid-vapor phase-change cooling has a significant potential to facilitate the development of highly dense electronics by leveraging latent heat during the phase transition to remove heat from hotspots. A promising form of liquid–vapor phase-change cooling is coalescence-induced jumping droplet condensation, where droplet growth results in coalescence

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.

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.
