Experimental study on the formation of two axial jets of cavitation bubbles near soft membranes with different thicknesses

AIP Advances, 2022
A cavitation bubble collapses non-spherically, splits into two smaller bubbles, and induces two axial jets flowing in opposite directions near a soft membrane. The soft membrane is deformed and even pierced after the impact of the downward jet.

A conservative coupling algorithm between a compressible flow and a rigid body using an Embedded Boundary method [PDF]

, 2012
This paper deals with a new solid-fluid coupling algorithm between a rigid body and an unsteady compressible fluid flow, using an Embedded Boundary method. The coupling with a rigid body is a first step towards the coupling with a Discrete Element method.
