A linearized theory of the forced radial oscillations of a gas bubble in a liquid is presented. Particular attention is devoted to the thermal effects. It is shown that both the effective polytropic exponent and the thermal damping constant are strongly dependent on the driving frequency. This dependence is illustrated with the aid of graphs and numerical tables which are applicable to any noncondensing gas–liquid combination. The particular case of an air bubble in water is also considered in detail.read more

Bubble Dynamics and Cavitation
TL;DR: The first analysis of a problem in cavitation and bubble dynamics was made by Rayleigh (1917), who solved the problem of the collapse of an empty cavity in a large mass of liquid.

Linear pressure waves in bubbly liquids: Comparison between theory and experiments
TL;DR: In this article, the authors present a rigorous model for the propagation of pressure waves in bubbly liquids and show that the model works well up to volume fractions of 1% to 2% provided that bubble resonances play a negligible role.
