本文结合像素分析方法和高速摄影技术进行了液滴撞击倾斜湿壁的实验研究，并观察了波纹板分离器中的实验现象。获得了扩展或形成树冠的We上限(pv(2)D/mu)和We下限。得出以下结论： 1、液滴以常规速度冲击斜面，产生飞溅、隆起但无飞溅、铺展； 2、液滴倾斜角对铺展因子影响较大，而We对铺展因子影响较小。 3、液滴低速撞击斜面，产生低速铺展、喷射、部分回弹、完全回弹结果。 4、随着角度的增大，扩展或形成冠度的We上限和We下限增大。 (C) 2019 Elsevier Ltd. 保留所有权利。
In this paper, the experimental study of droplet impacting on inclined wetted wall is carried out by combining the pixel analysis method and high-speed photography technology, and the experimental phenomena in the corrugated plate separator are observed. The upper We (pv(2)D/mu) limit and the lower We limit of spreading or forming crown are obtained. The following conclusions are drawn: 1. Droplet impacting on the inclined surface at conventional velocity to produce splashing, crown but no splashing, and spreading; 2. The inclination angle of droplet has great influence on spreading factor, while the We has little influence on spreading factor. 3. Droplet impact on the inclined surface at low velocity to produce low-velocity spreading, jetting, partial rebound, and complete rebound outcomes. 4. With the increase of the angle, the upper We limit and the lower We limit of spreading or forming crown increases. (C) 2019 Elsevier Ltd. All rights reserved.
