摘要

通过试验手段对震动条件下气泡在水中的上升过程进行了观测

主要分析了不同初始半径的气泡在不同频率、不同振幅的震动加速度作用下的行为特征。结果表明:振幅越大、频率越小、气泡越小

则气泡的水平偏移越大;振幅、频率以及初始气泡体积增大

均会导致气泡形变增大;随着震动幅度、频率的增加

气泡上升速度的振荡幅度略有减小。

Abstract

Experiments were carried out to observe the behavior of bubble rising in water excited by oscillation.The characteristics of bubbles with different initial diameters excited by oscillation with different frequencies and amplitudes were investigated.The results showed that

large amplitude

low oscillation frequency and small bubble would result in large horizontal deviation

and the bubble shape deformation would be greater when the oscillation frequency

amplitude and initial bubble volume got bigger.With an increase in vibration frequency and amplitude

the oscillation amplitude of bubble's rising speed would decrease slightly.
