For oscillations of gas bubbles in liquids, the polytropic exponent and thermal damping constant for the high frequency region have been re-evaluated based on the framework by Prosperetti [J. Acoust. Soc. Am. 61, 17–27 (2007)]. It is seen that the approximation of G1⪡1 in Prosperetti (1977) should be dropped for G1≥10−2. The ratios of bubble radii to wavelengths are the paramount parameters categorizing the behavior into three different regions.
