Size distributions of droplets produced by ultrasonic nebulizers [PDF]
Scientific Reports, 2019 AbstractIn many applications where small, similar-sized droplets are needed, ultrasonic nebulizers are employed. Little is known about the mechanism of nebulization, for example about what determines the median droplet size. Even less understood, is the droplet size distribution, which is often simply fitted with a log-normal distribution or assumed to

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

Continuous Growth of Droplet Size Variance due to Condensation in Turbulent Clouds [PDF]
, 2015 We use a stochastic model and direct numerical simulation to study the impact of turbulence on cloud droplet growth by condensation. We show that the variance of the droplet size distribution increases in time as t^{1/2}, with growth rate proportional to

Enable a Facile Size Re-distribution of MBE-Grown Ga-Droplets via In Situ Pulsed Laser Shooting
Nanoscale Research Letters, 2021 A MBE-prepared Gallium (Ga)-droplet surface on GaAs (001) substrate is in situ irradiated by a single shot of UV pulsed laser. It demonstrates that laser shooting can facilely re-adjust the size of Ga-droplet and a special Ga-droplet of extremely broad ...

Droplet Size Distribution in Spray
Chemical engineering, 1969 スプレーノズル先端で形成される薄膜の激粒化過程をランダム・ウォークモデルから考察し, 生成される液滴の粒径分布が対数正規分布となることを示した。さらに最大粒径を考え, 反射壁のあるランダム・ウォークを用いて対数正規分布を補正すれば, 実測値とよい一致を示すことが判った。平均粒径は, 最大粒径と対数標準偏差とから容易に計算できる。

Size distribution theory for jumping-droplet condensation [PDF]
Applied Physics Letters, 2019 Jumping-droplet condensation is promising for various applications where the droplet size distribution plays a key role in the overall system performance. Despite being extensively studied in recent works, inconsistencies existed in previous size distribution models as the droplet growth and removal mechanisms were often not properly described.
