Abstract
When small bubbles containing air or other gases are dispersed in water, the resulting acoustical properties differ a great deal from those of water even if the gas concentration by volume is only.a few percent. The speed of sound is significantly lower than in pure water and effects of dispersion and attenuation brought about by the presence of the bubbles alter the propagation of sound waves. In what follows the most important features of propagation of sound in bubbly liquids are dealt with. In many practical applications such as propagation of pressure waves in steam-water mixtures or under water explosions, the amplitude of the waves is not small. Attention therefore has to be given to waves of finite amplitude as well. These finite amplitude waves may develop into shock waves the structure of which is discussed.
