Probabilistic derivation of droplet velocity using quadrature method of moments
Open Engineering, 2023 Accurately prediction of dispersion and polydispersity of droplet flow is not a trivial task due to the complex behavior of the droplet size distribution (DSD) and the strong state of the instantaneous velocity of a droplet on the shape and size of the ...

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。

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,

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 ...

Predicting Droplet Size Distributions of Emulsions Produced in a Sonolator [PDF]
Industrial & Engineering Chemistry Research, 2020 Producing emulsions continuously compared to in batch production has many benefits, such as increased speed and agility of production. A Sonolator, a device similar to a high-pressure homogenizer, is capable of this continuous production. In this paper, the size of droplets produced during emulsification has been investigated for various orifice ...

Droplet Size Distribution in Sprays Based on Maximization of Entropy Generation
Entropy, 2003 : The maximum entropy principle (MEP), which has been popular in the modeling of droplet size and velocity distribution in sprays, is, strictly speaking, only applicable for isolated systems in thermodynamic equilibrium; whereas the spray formation ...
