Droplet heat transfer on micro-post arrays: Effect of droplet size on droplet thermal characteristics

International Journal of Heat and Fluid Flow, 2017
Abstract Heat transfer towards a water droplet from hydrophobic micro-post array surface is considered while mimicking the environmental temperatures. Micro-post arrays are created on a silicon wafer surface via lithography technique. The textured surfaces are replicated by polydimethylsiloxane (PDMS) to achieve an optical transmittance.

Study of Ion Transfer Coupling with Electron Transfer by Hydrophilic Droplet Electrodes

Analytical Chemistry, 2015
In a hydrophilic droplet three-electrode system, electroactive species within the droplet play very important roles in the electron-transfer (ET) process on the solid/electrolyte interface, which can then induce an ion-transfer (IT) reaction at the liquid/liquid interface.

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.

Visualization of Mass Transfer during Droplet Formation

Chemical Engineering & Technology, 2019
AbstractThe impact of mass transfer in liquid‐liquid extraction during droplet formation in a quiescent continuous phase was investigated. The impact of droplet size, concentration, and formation rate on a hanging droplet was analyzed via laser induced fluorescence (LIF) using rhodamine 6G as tracer in the system of toluene and acetone in water.

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

Mass transfer into droplets undergoing reactive extraction

Chemical Engineering and Processing: Process Intensification, 2003
Abstract The mass transfer into droplets in metal extraction is investigated in the system ZnSO 4 –H 2 SO 4 /di(2ethylhexyl)phosphoric acid in isododecane. Results of equilibrium measurements and stirred cell experiments are described in a mathematical model based on gradients of chemical potential.

Heat-transfer measurements of evaporating liquid droplets

International Journal of Heat and Mass Transfer, 1978
The heat transfer to simulated (porous sphere) water and methanol droplets were measured in an atmospheric vertical hot air tunnel. The experiments were limited to a Reynolds number range of 200–2000, a free stream air temperature range of 150–960°C and a velocity range of 2.1–11.4 m/s. The experimental data can best be correlated by Nuf(1 + B) = 2 + 0.

Experiments on individual droplet heat transfer rates

International Journal of Heat and Mass Transfer, 1972
Abstract Experimental results for droplet heat transfer during splattering have been extended to smaller drop sizes than previously available through the use of an electrostatic drop generation device. Droplet diameters vary from 0.02 to 0.15 in.

Droplet transfer model for laser-enhanced GMAW

The International Journal of Advanced Manufacturing Technology, 2012
Laser-enhanced gas metal arc welding (GMAW) is a recent modification of conventional GMAW. It applies a low power laser to the droplet to obtain an auxiliary detaching force to help the detachment and achieve controlled metal transfer. As a primary parameter that affects the process and weld quality, the size of the droplet needs to be monitored and ...
