我们成功地实现了乙醇液滴在半圆柱形声波导中的非接触传输。该波导由振动底板和半圆柱形反射器组成，在波导中激励传播声场。液滴悬浮在波导横截面中驻波模式的节点位置处，并由水平方向上的行波分量传输。当液滴直径为1.5mm，质量为1.38g时，输送距离为65 mm，终端速度为2.3m/s。(C)2012日本应用物理学会
We have succeeded in the noncontact transportation of ethanol droplets inside a semi cylindrical acoustic waveguide. The waveguide was composed of a vibration bottom plate and a semi cylindrical reflector, and a propagating acoustic field was excited in the waveguide. The droplet was levitated at the nodal position of the standing wave mode in the cross section of the waveguide and transported by the traveling wave component in the horizontal direction. The transportation distance was 65mm and the terminal velocity reached 2.3 m/s when the droplet was 1.5mm in diameter and 1.38 g in weight. (C) 2012 The Japan Society of Applied Physics
