RUI: Twin-Fluid Atomization of Slurry Jet

研究了声波对高速空气雾化泥浆射流的影响。雾化液滴的大小将用高速相机在不同的共振声波波长下进行测量，该理论表明雾化更精细、更均匀。半经验模型将用于关联和解释牛顿和假塑性悬浮液的测量结果。目标是控制微米和亚微米液滴的产生，使其具有窄的尺寸分布。这项研究涉及到粉末生产、喷涂、煤浆燃烧以及压电材料的使用。该研究项目将涉及这个以本科生为主的院校的几名本科生和研究生(瑞提案)，那里超过一半的学生是少数民族。

The effect of the acoustic waves on the atomization of a slurry jet by high velocity air will be investigated. The atomized drop sizes will be measured with a high speed camera at different resonant acoustic wavelengths, where the theory indicates a finer and more uniform atomization. Semi- empirical models will be used to correlate and interpret the measurements with Newtonian and pseudoplastic suspensions. The goal is the controlled generation of micron and sub-micron droplets, with narrow size distribution. The research is relevant to powder production, spray coating, coal slurry combustion, and the use of piezoelectric materials. The research project will involve several undergraduate and graduate students in this predominantly undergraduate institution (RUI proposal), where more than half of students are minorities.
