Modeling drop size distributions

Progress in Energy and Combustion Science, 2002
There is abundant literature discussing the prediction of a representative drop diameter in a spray. However, there are relatively few publications discussing prediction of a drop size distribution in sprays. In the present paper, we review the three available methods for modeling drop size distributions: the maximum entropy method, the discrete ...

Drop size distribution and mean drop size in a pulsed packed extraction column

Chemical Engineering Research and Design, 2012
Abstract Drop size distribution and mean drop size are used for calculation of interfacial area available for mass transfer. In this study, the drop size distribution and Sauter mean drop diameter (d32) have been investigated using three different liquid systems in the absence of mass transfer in a pilot plant pulsed packed column.

A study on mean drop size and drop size distribution in an eductor liquid–liquid extractor

Separation and Purification Technology, 2018
Abstract In this work, Sauter mean diameter (SMD) and drop size distribution (DSD) are investigated in an eductor liquid-liquid extractor. The water/toluene liquid-liquid extraction (LLE) system was applied in the experiments. The jet length, the existence of venturi, the throat to nozzle area ratio, the projection ratio, and two phases flow rate ...

Size distribution of detached drops

Journal of Engineering Physics, 1989
The law governing the size distribution of detached gas-liquid streams of drops has been determined analytically, and a comparison is carried out against experimental data existing in the literature. The derived theoretical relationships offer an excellent description of existing experimental results.

Drop Size Distributions

2010
Drop size distributions are at least as important as mean drop sizes. Some spray applications require narrow size distributions (paint and respirable sprays), while some need wide ones (gas turbine engines). Other spray processes require very few small drops (agricultural or consumer product sprays) or very few large ones (waste incineration, IC ...

A new parametrization of the rain drop size distribution

IEEE Transactions on Geoscience and Remote Sensing, 1997
This paper revisits the problem of finding a parametric form for the rain drop size distribution (DSD) which (1) is an appropriate model for tropical rainfall, and (2) involves statistically independent parameters. Using TOGA/COARE data, the authors derive a parametrization which meets these criteria.

Airblast Atomization: Studies on Drop-Size Distribution

Journal of Energy, 1981
The influence of air velocity and liquid properties on drop-size distribution is examined using an airblast atomizer in which a flat liquid sheet is exposed to high velocity air on both sides. Both photographic and lightscattering techniques are employed to measure drop sizes.

Tropical rainfall drop‐size distribution

International Journal of Satellite Communications, 1990
AbstractBased on disdrometer measurements carried out in Brazil, this paper discusses the problem of rainfall drop‐size distribution in tropical areas and its effect on radiowave propagation at frequencies above 10 GHz. A comparison between Laws and Parsons and lognormal models is made.
