A theory for the impact of a wave breaking onto a permeable barrier with jet generation [PDF]

, 2013
We model a water wave impact onto a porous breakwater. The breakwater surface is modelled as a thin barrier composed of solid matter pierced by channels through which water can flow freely.

Jet formation from bubbles near a solid boundary in a compressible liquid. Numerical study of distance dependence

, 2020
A small, spherical bubble of high internal pressure is inserted into water at constant ambient pressure as a model of a laser-induced bubble. Its subsequent dynamics near a flat solid boundary is studied in dependence on the distance of the bubble to the
