Air Bubble Entrainment In Free-surface Turbulen... (FAST × 2025)

The free surface begins to deform slightly, but no air is yet trapped.

A surface cavity develops, reaching deeper into the water while the sides remain smooth. Air Bubble Entrainment in Free-Surface Turbulen...

The free surfaces enclose, releasing a single or group of air bubbles into the turbulent flow. Key Drivers and Models The free surface begins to deform slightly, but

Air entrainment is not a singular event but a multi-stage process driven by the instability of the air-water interface:
