论文摘要
使用高速摄影研究了我们在各种倾斜角度影响网格的液滴。发现液滴网状渗透可以通过粘贴网格完全抑制。已经通过实验确定了（We，α）平面（WE，α）平面中的相图。结果表明，无渗透和不完全穿透之间的过渡以及不完全穿透和完全穿透之间的过渡在与α中单调的跃迁之间的过渡。提出了一个简单的预测过渡阈值的模型，并通过与实验结果进行比较来验证。结果表明，倾斜角和网格开放区域分数都决定了穿透的类型。
Droplets with different Weber numbers We impacting meshes at various inclination angles were investigated using high-speed photography. It was found that the droplet mesh penetration can be completely suppressed by inclining the mesh. The phase diagrams in the (We, α) plane determining the expected type of penetration have been determined experimentally for meshes of various structures. It was shown that the Weber numbers for transition between no-penetration and incomplete penetration as well as for transition between incomplete penetration and complete penetration increase monotonically with α. A simple model for predicting the transition thresholds is proposed and is validated by comparisons with experimental results. It is shown that both the inclination angle and the mesh open area fraction determine the type of penetration.
