Calculation of a Nonuniform and Nonadiabatic Model of Sonoluminescence

A nonuniform and nonadiabatic model has been developed to research the gas dynamics within a bubble of sonoluminescence. The model includes three diffusive effects of gas viscosity, thermal conduction and radiative transport simultaneously, and calculations prove that they have important influences on the characteristics of sonoluminescence. The model has been solved numerically and gives the results of about 10⁴ K peak temperature and l00ps pulse duration which are consistent with recent experiments.
