Influence of the ambient pressure on free oscillations of bubbles in liquids

Theoretical results demonstrating the influence of the ambient pressure on free oscillations of gas and vapour bubbles in liquids are presented. Acoustic losses, which increase with the ambient pressure, are shown to be a major factor influencing the overall bubble behaviour. The analysis reveals in...

Description
Summary:Theoretical results demonstrating the influence of the ambient pressure on free oscillations of gas and vapour bubbles in liquids are presented. Acoustic losses, which increase with the ambient pressure, are shown to be a major factor influencing the overall bubble behaviour. The analysis reveals interesting facts about vapour bubbles, for which a minimum of the oscillation intensity is found at a certain ambient pressure.
