Abstract
In the present paper, wave propagation in liquids with oscillating vapor-gas bubbles is numerically investigated with a focus on the variations of the wave speed. A wide range of influencing parameters (including frequency, vapor mass fraction, bubble radius and void fraction) on the phenomenon are shown and discussed. According to the influences of frequency, the wave speed in the vapor-gas bubbly liquids could be categorized into three regions by two critical frequencies. In regions 1 and 3, the wave speed is frequency-independent while in region 2, the wave speed varies strongly with the frequency. Vapor mass fraction shows remarkable influences on the wave speed in regions 1 and 2 together with the critical frequencies separating the two regions. Finally, the influences of variations of the ambient temperature on the wave speed are discussed with demonstrating examples.
