Experimental and numerical study of droplet motion and separation induced by aerodynamic and mechanical forces

液滴的运动可以以不同的方式开始，如剪切流、振动力或梯度表面。有些影响可以叠加，因此一些相互作用没有详细研究。目前的建议介绍了为此目的的实验和数值研究。本研究涵盖了由机械振动和叠加剪切流引起的液滴运动。在这种情况下，将实现一维和二维振动冲击。研究的目的是确定液滴运动的相图作为液滴大小、振动频率和振幅以及剪切流速的函数。此外，还将研究相同实验参数下的液滴分离。此外，还将采用流体体积模型和附加的接触角迟滞模型进行数值模拟。

The motion of droplets can be initiated in different ways such as shear flows, vibrational forces or gradient surfaces. Some of the influences can be superposed, whereupon some interactions are not investigated in detail. The current proposal introduces an experimental and numerical study for this purpose. This study covers droplet motion induced by mechanical vibrations and superposed shear flows. In this context a single as well as a two dimensional vibrational impact will be realized. The aim of the study is the determination of phase diagrams of the droplet motion as a function of droplet size, vibrational frequency and amplitude as well as the shear flow velocity. Furthermore, droplet separation due to the same experimental parameters will be investigated, too. Furthermore, numerical simulations with a Volume-of-Fluid model with additional models for the contact angle hysteresis will be made.
