The requested high speed imaging facility will enable two exciting investigations, i.e., study of oscillations of a drop in contact with a surface when a shearing airflow is present, and drop impact onto particles. Understanding the role that drop oscillation plays in dislodging (or shedding) a drop in presence of a shearing airflow is important for applications such as condensers, fuel cells and runback of drops and their ensuing freezing in icing of airfoils (in aeronautics or wind turbine applications). Particle drop impact is a core process in any fluidized bed spray interactions, e.g. upgrading of heavy oil in a fluid catalytic cracking reactor, or coating of drug particles.

所需的高速成像设施将实现两项令人兴奋的研究，即研究存在剪切气流时液滴与表面接触的振荡，以及液滴对颗粒的冲击。了解液滴振荡在存在剪切气流的情况下移动（或脱落）液滴的作用对于冷凝器、燃料电池和液滴回流以及随后在翼型结冰中冻结（在航空或风力涡轮机应用中）等应用非常重要。颗粒掉落冲击是任何流化床喷雾相互作用的核心过程，例如流化催化裂化反应器中重油的升级，或药物颗粒的涂层。
