Experimental analysis on bubble rising behavior excited by oscillation

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.
