Abstract

The behavior of a permanent gas bubble in liquids under oscillating pressure fields is studied by a linearized theory. The derived thermodynamic relation tends to indicate average isothermality for high frequency limit, contrary to the usual intuitive reasonings. The growth of the gas bubble under the oscillating pressure fields due to the effect of rectification of mass is also investigated. The effect is small, being of second order, but accumulating. The absence of resulting large bubbles is explained briefly by the considerations on the stability of spherical shape of the bubbles.
