Abstract
Based on the interaction among non-spherical bubbles, this study investigated the dynamic behavior and internal temperature changes of non-spherical oscillating bubbles in a high-intensity sound field from a theoretical perspective. Under the condition of the same initial parameters, when the sound field frequency approaches megahertz, the research found that in liquids with different viscosities and surface tensions, the temperature inside the bubbles is difficult to reach the high temperature required for sonoluminescence.
