Numerical simulations of non-spherical bubble collapse.
A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a bubble near a planar rigid surface and in a free field are analysed. Collapse times, bubble displacements, interfacial velocities and surface pres...
متن کاملAnalytical approximations for the collapse of an empty spherical bubble.
The Rayleigh equation 3/2R+RR+pρ(-1)=0 with initial conditions R(0)=R(0), R(0)=0 models the collapse of an empty spherical bubble of radius R(T) in an ideal, infinite liquid with far-field pressure p and density ρ. The solution for r≡R/R(0) as a function of time t≡T/T(c), where R(T(c))≡0, is independent of R(0), p, and ρ. While no closed-form expression for r(t) is known, we find that r(0)(t)=(...
متن کاملBubble-Induced Cave Collapse
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 while they were in the cave, attributing this to their unintentional (and frowned upon) physical contact with the cave walls or the aforementi...
متن کاملShock-Induced Bubble Collapse versus Rayleigh Collapse
This paper compares two physical mechanisms for the collapse of a bubble near a rigid wall: a traveling shock-induced collapse and a Rayleigh-like collapse due to a uniform rise of the pressure around the bubble. A multi-material compressible flow solver capable of handling material interfaces under high pressures is used to investigate these two scenarios for different levels of the driving pr...
متن کاملObservation of Spherical Growth and Collapse of a Spark Bubble in Water
An experiment is described where the evolution of a single vapor bubble in water was observed. The bubble was generated by an electric spark between two electrodes designed to provide minimal interference to both liquid motion and the propagation of acoustic waves. The electrostatic energy of the discharge was varied to obtain vapor bubbles with radii ranging from about 2 to 5 centimeters. A hi...
