Single droplet displacement infrared action spectroscopy [PDF]

open access: yesNature Communications
Aqueous 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.

Insecticide spray drift reduction with different adjuvants and spray nozzles [PDF]

open access: yesRevista 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]

open access: yesEngenharia 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

open access: yesAgronomy, 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 ...

Lattice Boltzmann simulation of droplet behaviour in microfluidic devices [PDF]

open access: yes, 2009
We developed a lattice Boltzmann model to investigate the droplet dynamics in microfluidic devices. In our model, a stress-free boundary condition was proposed to conserve the total mass of flow system and improve the numerical stability for flows with ...

EFFECT OF NOZZLES, APPLICATION RATES, AND ADJUVANTS ON SPRAY DEPOSITION IN WHEAT CROPS [PDF]

open access: yesEngenharia Agrícola, 2019
The use of insecticides is common in pest management in wheat crops but may lead to higher production costs and environmental contamination. Therefore, a more comprehensive and uniform distribution of plant protection products in the desired target is ...

Atomization Characteristics of a Hollow Cone Nozzle for Air-Assisted Variable-Rate Spraying

open access: yesAgriculture, 2023
During variable-rate spraying in orchards, the atomization characteristics and distribution of droplets in and out of the target area can be affected by the sprayer pressure. In this study, a variable-rate spraying control system test bench was designed,
