Mass transfer within oscillating liquid droplets

The Canadian Journal of Chemical Engineering, 1970
AbstractAll existing relations describing mass transfer within oscillating droplets were critically compared with experimental data in which resistance to transfer is predominantly inside the droplet. Several new relations are also developed to estimate oscillating droplet extraction efficiencies, one of which is recommended in view of its theoretical ...

Droplet Cooling Heat Transfer Model Validation

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">Heat transfer by phase change is an attractive method of cooling since large amounts of heat can be removed with relatively small temperature differences. Droplet cooling is one method whereby very high heat transfer rates coupled with good temperature uniformity across surfaces can be provided, which is important ...

Heat transfer during condensing droplet coalescence

International Journal of Heat and Mass Transfer, 2018
Abstract Dropwise condensation can yield heat fluxes up to an order of magnitude higher than filmwise condensation. Coalescence is the primary mode of growth for condensing droplets above a small threshold size (e.g., radius r > 2 μm for water at 1 atm), but no prior studies have quantitatively assessed heat transfer during coalescence.

Droplet transfer in two-phase annular flow

International Journal of Multiphase Flow, 1983
Abstract The tracer method, adopted by a number of experiments for the measurement of the rate of liquid interchange between the wall layer and the dispersed phase in a fully developed annular flow, has been critically examined on the basis of a more accurate description of the flow behavior of entrained droplets.

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

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.
