Abstract: The temperature of the gas within a spherical cavity driven by a sinusoidal pressure field is calculated using an existing model [H. G. Flynn, J. Acoust. Soc. Am. 57, 1379–1396 (1975)] for cavitation dynamics. The temperature field in the liquid surrounding the bubble also is calculated with this model. For this work it is assumed that temperature variations are due to heat conduction only, although corrections for evaporation, condensation, etc., may be included if desired. Because the temperature T in the liquid at the cavity interface is allowed to vary (which reduces heat conduction by reducing the thermal gradient at the interface) the effect of holding T fixed is investigated. Results are presented for argon-filled and air-filled cavities in water or various organic liquids. [Work supported by ONR and NIH.]
