研究了一种用于控制和捕获空气中微细颗粒的声学谐振器系统。需要仔细考虑谐振器设计中使用的材料的厚度和性能的影响，以确保优化谐振器。这是通过分析和有限元建模，以及在0.8到2.0 MHz频率范围内的空气声衰减的函数预测来实现的。这导致了可能的操作频率范围的预测，以获得粒子操作。实验结果表明，可以很好地捕获直径小至15 μ m的粒子。(C) 2015 Elsevier B.V.版权所有
An acoustic resonator system has been investigated for the manipulation and entrapment of micronsized particles in air. Careful consideration of the effect of the thickness and properties of the materials used in the design of the resonator was needed to ensure an optimised resonator. This was achieved using both analytical and finite-element modelling, as well as predictions of acoustic attenuation in air as a function of frequency over the 0.8 to 2.0 MHz frequency range. This resulted in a prediction of the likely operational frequency range to obtain particle manipulation. Experimental results are presented to demonstrate good capture of particles as small as 15 mu m in diameter. (C) 2015 Elsevier B.V. All rights reserved.
