The role of absorbed energy on the oscillation mode of an air bubble in a cavitation-induced acoustic field

<p>The dataset contains the images (.tiff) and pressure signals (.lvm) of an evolving laser-induced cavitation bubble (time history) and its interaction with a gas bubble at different conditions.</p>

<p>The shape oscillation of an acoustically-excited gas bubble is not fully understood despite applications from biomedical to sound propagation in oceans. We present the first detailed investigation and characterization of air bubble oscillations due to a cavitation-induced acoustic field and quantify the energy needed to excite the growth of sub-harmonics and super-harmonics. We show how the acoustic intensity and bubble size govern the bubble energy absorption and discover the relationship determining how the absorbed energy generates ripples on the bubble surface, their growth, and ultimate bubble breakup. This work will enable the physics community to explain fundamental bubble-bubble and cavitation-bubble interactions.</p>
