Adaptive method of lines for multi-component aerosol condensational growth and CCN activation [PDF]
Geoscientific Model Development, 2011 The process of formation of cloud droplets on an ensemble of aerosol particles is modelled by numerous investigators using the method of lines (MOL). The method involves discretisation of the aerosol size spectrum into bins whose positions evolve with ...

Drift Potential Characteristics of a Flat Fan Nozzle: A Numerical and Experimental Study
Applied Sciences, 2022 This study explores the drift potential characteristics of a flat fan nozzle. The atomization and drift characteristics of fan-shaped pressure nozzles were studied at a spraying height of 0.6 m and a lateral wind speed of 0–6 m/s through a combination of

Impact of high- and low-vorticity turbulence on cloud–environment mixing and cloud microphysics processes [PDF]
Atmospheric Chemistry and Physics, 2021 Turbulent mixing of dry air affects the evolution of the cloud droplet size spectrum via various mechanisms. In a turbulent cloud, high- and low-vorticity regions coexist, and inertial clustering of cloud droplets can occur in low-vorticity regions.

Toward an Understanding of the Indirect Climatic Effect of Aerosols [PDF]
, 2003 This thesis is motivated by the need to improve our understanding of the aerosol indirect effect. The activation of aerosol into cloud droplets has been extensively studied, using a comprehensive numerical cloud droplet activation model. Using this model,

Spectrum of spray droplets with different nozzles and adjuvants
Revista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences, 2020 Successful application of agrochemicals depends on factors such as the droplet size, nozzle type and solution composition. In this context, the objective of this study was to evaluate the spectrum of spray droplets with different spray nozzles by means of direct measurement.
