Cavitation bubble-particle interactions induced by shock waves

Processing applications involving cavitating particle suspensions exhibit cavitation-induced
particle fragmentation, separation, and cleaning. Since many of these processes comprise
heterogeneous cavitation nucleation on suspended particles, gaining a deep understanding
of the mechanisms at play at a single particle level is crucial for effective control.
In these experiments will be conducted using high-speed imaging of particle-water suspensions
exposed to shock waves with a rarefaction part of a few MPa. Using X-ray phase-contrast
imaging, the visualizations will reveal the bubble morphology and allow for a detailed
analysis of its dynamics, including interior phenomena. The equipment for this work has alrady been used before during IHME22. And is standard CE tabletop medical shock-wave device for kidney stone tretments brought by TH Zurich team.
