Formation Principle and Characteristics of Self-Supercharging Pulsed Water Jet
Chinese Journal of Mechanical Engineering, 2022 High-pressure pulsed water jet technology has considerable development potential in the field of rock fragmentation. To overcome the shortcomings of existing pulsed jets, a self-supercharging pulsed water jet (SSPWJ) generation method is proposed, which ...

Numerical study of the collapse of a bubble subjected to a lithotripter pulse [PDF]
, 2006 The collapse of a bubble subjected to a lithotripter pulse is studied numerically. The goal is to record the pressure exerted along the stone, as a measure of potential stone damage. It is found that the pressure due to buble collapse is much larger than

Scattering of a Plane Acoustical Wave by a Spherical Obstacle [PDF]
, 1965 The long-time behavior of the scattered field produced by a plane acoustical pulse stalking a spherical obstacle is investigated. Incident pulses are taken that represent a unit step in potential (or equivalently delta function pulse in pressure), an ...
