Abstract
In present chapter, a brief discussion was conducted in order to reveal the energetic effect of the different energy parameters (PV work, mass transport, reaction heat and heat exchange) in a multibubble system. Additionally, the overall energetic variation of this bubble's population was visualized. Interesting observations have been inferred from this theoretical study. First, it was observed that, during expansion or bubble lifetime periods, the impact of each of the energy parameters in a multibubble system is not ultrasound frequency dependent conversely to an early studies of a single bubble system. Secondly, for frequencies bellow 362 kHz, it was demonstrated that whatever oscillation duration (expansion, collapse or bubble lifetime), the controlling key of power density is the single bubble system. On the contrary, above 362 kHz, it was found that the number of acoustic bubbles is the key parameter for the overall power density of the multibubble system and for each of the energy parameters.
