Alternative model of single-bubble sonoluminescence

摘要: A model of single-bubble sonoluminescence (SBSL) is constructed. In the model, temperature assumed to be spatially uniform inside bubble except at thermal boundary layer near wall even strong collapse based on theoretical results Kwak and Na [Phys. Rev. Lett. 77, 4454 (1996)]. effect kinetic energy gases taken into account, which heats up whole when stop their motions end collapse. a in water containing air consist mainly argon hypothesis Lohse et al. 78, 1359 (1997)]. Numerical calculations under SBSL condition reveal that considerably. It also clarified vapor molecules $({\mathrm{H}}_{2}\mathrm{O})$ undergo chemical reactions heated interior decrease suggested originates radiation from rather than local point (the center) by converging spherical shock wave widely previous theories SBSL.
