A Study of Liquid Streams in Vacuum and Higher Pressure Environments (REU Supplement)

关于液流分解成液滴的研究还有待继续。这项工作在很大程度上是实验性的，将利用载波频率上的幅度调制来探索由流动喷嘴中诱导的压力振荡所驱动的破裂行为。这种方法可以产生非常低的液滴速度分散体。要研究环境气体压力的影响，以及控制液滴碰撞以产生新的液体形式。陶瓷前驱体、喷涂和网络制造等加工应用将受益于控制液滴形状和动态的能力的增强。

A study of the break-up of a liquid stream into droplets is to be continued. The work is largely experimental, and will explore break-up behavior driven by pressure oscillations induced in the flow nozzle, using amplitude modulation on a carrier frequency. Very low droplet speed dispersion can be produced this way. The effect of ambient gas pressure is to be investigated, as well as controlled drop collisions to produce novel liquid forms. Processing applications, such as ceramic precursors, spray coating, and net-form manufacturing will benefit from an increased ability to control the shape and dynamics of liquid drops.
