Entrainment and the droplet spectrum in cumulus clouds
Quarterly Journal of the Royal Meteorological Society, 1982AbstractThe model of the development of the droplet spectrum in cumulus clouds described by Mason and Jonas (1974) has been used to calculate the spectrum in penetrating downdraughts and the changes which occur when a region of dry air resulting from such a downdraught is subsequently forced to rise. It is shown that evaporation in the downdraught does

Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 2010
The most important factor affecting efficacy and drift of pesticide applications is the droplet spectrum. To measure pesticide drift, researchers utilize fluorescent tracers to rapidly quantify spray deposition. Although fluorescent tracers have been used for more than 50 years, no experiments have been performed on the effect they have on the ...

Sampling Techniques to Determine Droplet Size Spectrum for Fan Nozzles
1990Droplet size measurements obtained by sampling at discrete spray plume locations were compared to those obtained by sweeping the spray plume from fan nozzles through the sampling area of a laser droplet imaging probe. A mixture of water, 2.5% Tenneco 500/100 solvent and 0.5% Titron X-100 adjuvant was sprayed through flat spray and even flat spray ...

Droplet Spectrum Analysis from Artificially Generated Rain Showers [PDF]
Journal of Irrigation and Drainage Engineering, 2014 AbstractSevere droughts were experienced by many southerly states of the Indian subcontinent during the past decade. Farmer suicides were reported from the state of Andhra Pradesh year after year, especially when the monsoons failed. The government of India conducted expensive rain enhancement experiments through artificial cloud seeding; this did ...

Polydispersed droplet spectrum and exergy analysis in wet steam flows using method of moments [PDF]
Applied Thermal Engineering, 2021 In steam turbine flow, the complex droplet spectrum caused by nonequilibrium condensation is necessary to be modeled accurately to predict the droplet behavior and estimate the exergy destruction and erosion rate.

Infrared Spectrum of Fulvenallene and Fulvenallenyl in Helium Droplets
The Journal of Physical Chemistry A, 2019Fulvenallene is the global minimum on the C7H6 potential energy surface. Rearrangement of fulvenallene to other C7H6 species and dissociation to produce fulvenallenyl radical (C7H5) is carried out in a continuous-wave SiC pyrolysis furnace at 1500 K. Prompt pick-up and solvation by helium droplets allows for the acquisition of vibrational spectra of ...

Spray atomizer droplet spectrum measurement
The Canadian Journal of Chemical Engineering, 1980AbstractThe gamma function distribution is used to discuss droplet size variation for flat fan and round orifice atomizers. A technique of using multiple‐probe devices to measure droplet size, distribution and flux when the form of the distribution is known is described.

Study on droplets characteristics used for infrared spectrum suppression
2015 IEEE International Conference on Mechatronics and Automation (ICMA), 2015A model is developed to predict the motion and evaporation characteristics of spray droplets which are used for infrared stealth based on the assumptions of single droplet and spherical symmetry. There are lots of parameters like sprays properties and ambient conditions that affect the stealth process, but only several factors such as wind, irradiation,
