• The initial-boundary value problem is solved for acoustic disturbance caused by asource in the uniform bubbly liquid flow without the velocity slip. The solution showsthe transient and final characteristics of four modes of unusual acoustic wave,resulting from the interaction between the volume oscillation of bubbles and the wavemotion in the flowing medium. The solution also shows that the energy distributedfor each mode is different depending on the frequency of the source and on Machnumber of the main stream. For high frequency, the ratio of propagation mode tocutoff mode is very small at low Mach number but large at high Mach number. Thereis a possibility that the energy of cutoff modes is expended to break up bubbles.
