摘要: 以Al粉为示踪粒子,对甘油+水的混合液施加一个连续可调的振动振幅;利用CCD摄像头采集流场信号,首次观察到了不同振幅下液体表面不同的谐振现象;并测量了不同谐振点时液体表面流动的速度;用实验现象清晰的反映了液体表面行为随振幅的变化.

关键词: 低频振动, 谐振现象, 表面流动

Abstract: A continuously adjustable vibration amplitude was induced in glycerite water solution. Monitored by CCD, with Al tracer particles for flow visualization and velocity measurements, various resonance phenomena on the fluid surface were firstly observed. The surface streaming velocities at different resonance points were measured. The behavior of the fluid surface under a gradually increasing amplitude can be showed clearly by the experiment.

Key words: low-frequency vibration, resonance phenomena, surface flow
