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.
