Droplet spectrum at different vapour pressure deficits1 [PDF]
Revista Ciência Agronômica, 2016 An efficient pesticides spraying depends a lot in psychrometric conditions, mainly if it is using fine droplets, once climatic conditions may cause droplets evaporation and consequent financial loss to the farmer.

Droplet distribution spectrum effects on dry ice growth on cylinders [PDF]
Cold Regions Science and Technology, 2019 Abstract A detailed parametric analytical study along with a series of viscid multiphase numerical simulations of ice accretion were performed in comparison with experimental data of ice accretion on a 30 mm diameter cylinder. The study was performed for droplet distribution spectra, Langmuir (A-J), in addition to an experimental droplet distribution

Pulse Width Modulation on the Droplet Spectrum and Velocity of Spray Nozzles [PDF]
Agriculture (Switzerland)Pulse width modulation (PWM) allows for the real-time flow rate adjustment of spray nozzles without changing system pressure, indicating that PWM is a promising technology for improving the quality of pesticide applications. However, its effect on the droplet formation process is not yet fully understood.

Single droplet displacement infrared action spectroscopy [PDF]
Nature CommunicationsAqueous microdroplets have fascinated scientists with unique properties that deviate from bulk solutions. Understanding microdroplet chemistry has been limited by few spectroscopic measurements on single well-defined microdroplets.

Effect of Image Segmentation Thresholding on Droplet Size Measurement
Agronomy, 2022 Droplet size spectrum is a key factor in pesticide application because it affects the biological efficacy of a treatment in terms of target coverage, environmental impact in terms of evaporation, drift and run-off, and operator’s safety in terms of ...

The possibilities of droplet spectrum regulation at application of plant protection products [PDF]
Research in Agricultural Engineering, 2005 Verification of the possibilities of a droplet spectrum regulation due to the change of working pressure, as well as the change of the size of the discharge orifice of a nozzle, was undertaken in laboratory conditions by measurement of the size of a ...

Modulation of the droplet spectrum by working pressure, adjuvants, and herbicides [PDF]
Revista CeresThe droplet spectrum is a crucial factor in optimizing herbicide efficacy and minimizing spray drift. This study evaluated the effects of working pressure (100 to 600 kPa) and six adjuvants on droplet size, both in the absence and presence of herbicides,

Droplet spectrum of a spray nozzle under different weather conditions [PDF]
REVISTA CIÊNCIA AGRONÔMICA, 2018 ABSTRACT The application of pesticides is always susceptible to losses through evaporation and drift of the spray droplets. With these losses, a smaller amount of pesticide reaches the target, possibly impairing the efficiency of phytosanitary control.
