Methods of theoretical study of vibrational phenomena in liquids--comparative analysis

In this review, existing theoretical models of vibrational phenomena in liquids are analyzed and compared. Most attention is paid to sonoluminescence, sonolysis and related phenomena. The criteria of selection of the optimal theoretical model involve analyzing experimental results, its usefulness for evaluation of thermodynamic and other parameters of the liquid under vibration, simplicity of the mathematical solution and the time needed for computing. It is concluded that, according to these criteria, the optimal (between existing models) is the chemical model of vibration in liquid, while the best perspectives are for its combinations with other models.
