Cavitation Clusters in Lipid Systems – The Generation of a Bifurcated Streamer and the Dual Collapse of a Bubble Cluster


Over the past decade several studies have reported the use of high intensity ultrasound (HIU) to induce the crystallization of lipids. The effect that HIU has on lipid crystallization is usually attributed to the generation of cavities but acoustic cavitation has never been fully explored in lipids. The dynamics of a particular cavitation cluster next to a piston like emitter in an oil, was investigated in this study. The lipid systems, which are important in food processing, are studied with high-speed camera imaging, laser scattering and pressure measurements. A sequence of stable clusters were noted. In addition, a bifurcated streamer was detected which exists within a sequence of clusters. This is shown to originate from two clusters on the PLE tip oscillating with an 1800 phase relationship with respect to one another. Finally, the collapse phase of the cluster is shown to involve a rapid (µs) two stage process. These results show that the dynamics of cluster formation and collapse is driven by HIU power levels and might have implications in lipid sonocrystallization.
