Planar jets in collapsing cavitation bubbles

Experimental investigations of three laser-induced synchronized bubbles

“…These are all problems caused by the directionality of multiple pressures. The situation can be approximated as described elsewhere [52] , [53] , [54] , [55] , [56] , [57] partly. Here, we ignore the little angular shift due to the screen effect and symmetry.…”

Cavity collapse near slot geometries

“…Simple potential flow models using mirror sinks have been used to predict the jet direction in limited geometries (Kucera & Blake 1990; Tagawa & Peters 2018; Molefe & Peters 2019). More complex boundary integral methods and boundary element methods have been applied, typically to simulate how the surface of the bubble moves during collapse (Kucera & Blake 1990; Harris 1996; Li et al 2016; Brujan et al 2019). In this research a simplified boundary element method is used to predict the jet direction without resolving how the surface of the bubble moves over time.…”

“…Some more complex geometries have been studied, such as parallel boundaries closed at one end (Brujan, Takahira & Ogasawara 2019), semi-infinite boundaries (Kucera & Blake 1990), near combinations of a free surface and an inclined flat boundary (Zhang et al 2017), inside a set of concave corners (Kucera & Blake 1990; Brujan et al 2018; Tagawa & Peters 2018; Wang et al 2020) and inside rectangular and triangular channels (Molefe & Peters 2019). A recent experimental study has investigated how a ridge-patterned structure can affect the bubble surface evolution and jet dynamics when a bubble is generated on the ridge and between the ridges (Kim & Kim 2020).…”

Growth of N-dimensional spherical bubble within viscous, superheated liquid: Analytical solution

“…The dynamics of a growth or a collapse of vapour/gas bubbles are an area of great interest with several applications of science as dynamics of fluids, biomedical physics, and engineering and bioengineering applications [1][2][3][4][5]. The dynamics of vapour/gas bubbles are strongly dependent on many physical parameters such as the parameter of pressure of the vapour/gas that contained on it.…”
