Droplet spectrum at different vapour pressure deficits1
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

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,

Insecticide spray drift reduction with different adjuvants and spray nozzles [PDF]
Revista Brasileira de Engenharia Agrícola e Ambiental, 2021 Insecticide spray drift can lead to reduced control efficiency and loss of product to the environment. Thus, we conducted a study to evaluate the effect of different spray nozzles and the addition of adjuvants in insecticide spray on the resulting ...

NUMERICAL SIMULATION AND EXPERIMENTAL ANALYSIS OF SPRAY FIELD OF IMPINGEMENT NOZZLE [PDF]
Engenharia Agrícola, 2023 The shape of a spray droplet from a flat-fan nozzle in the plant protection sector is similar to a ‘U shape’, the middle particle size being small but the diameter of both sides being too large.

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 ...
