Failure Mechanisms of Hollow Fiber Supported Ionic Liquid Membranes
Membranes, 2016 Hollow fiber supported ionic liquid membranes (SILMs) were tested using the bubble point method to investigate potential failure modes, including the maximum transmembrane pressure before loss of the ionic liquid from the support.

Eulerian-Lagrangian method for simulation of cloud cavitation [PDF]
, 2017 We present a coupled Eulerian-Lagrangian method to simulate cloud cavitation in a compressible liquid. The method is designed to capture the strong, volumetric oscillations of each bubble and the bubble-scattered acoustics.

Non-spherical collapse of an air bubble subjected to a lithotripter pulse [PDF]
, 2008 In order to better understand the contribution of bubble collapse to stone comminution in shockwave lithotripsy, the shockinduced and Rayleigh collapse of a spherical air bubble is investigated using numerical simulations, and the free-field collapse ...

Observations and scaling of travelling bubble cavitation [PDF]
, 1995 Recent observations of growing and collapsing bubbles in flows over axisymmetric headforms have revealed the complexity of the ‘micro-fluid-mechanics’ associated with these bubbles (van der Meulen & van Renesse 1989; Briancon-Marjollet et al.

Numerical simulation of the backscattering of pressure waves from a bubble interface
Nihon Kikai Gakkai ronbunshu, 2015 The direct numerical simulations are conducted for the backscattering of incident pressure waves from a bubble with the ghost fluid method in order to understand the formation of secondary cavitation in the high intensity focused ultrasound (HIFU). It is
