Modifying the cavitation bubble collapse in the erosive regime with a surface bar structure [PDF]
Ultrasonics SonochemistryThe collapse of cavitation bubbles near surfaces can cause severe erosion, posing significant risks to fast-rotating turbines. Previous studies suggest that the energy concentration of shock waves during non-spherical collapse is a potential mechanism ...

Bubble-induced cave collapse. [PDF]
PLoS ONE, 2015 Conventional wisdom among cave divers is that submerged caves in aquifers, such as in Florida or the Yucatan, are unstable due to their ever-growing size from limestone dissolution in water. Cave divers occasionally noted partial cave collapses occurring
