| description abstract | The velocity of sound at a frequency much greater than resonance in a bubbly air-water mixture has been measured for varying void fractions in a “pool” system. Only measurements of acoustic velocity well below resonance for varying void fraction, or near resonance for a few low void fractions, were previously available. The results presented in this paper show marked differences in the velocity of sound at high frequency (500 kHz) compared with existing low-frequency data. Existing theory, for low void fractions, is discussed in relation to phase, group, and signal velocity, with the limitations at high void fractions being given. The application of the technique for determining void fractions in two-phase flow systems is discussed. | |
