Fluid simulations with atomistic resolution : a hybrid multiscale method with field-wise coupling [PDF]

, 2013
We present a new hybrid method for simulating dense fluid systems that exhibit multiscale behaviour, in particular, systems in which a Navier–Stokes model may not be valid in parts of the computational domain.

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.
