文摘
- •
Contact angle dynamics in the initial stages of droplet impact at low Weber numbers.
- •
The dynamic CAs significantly differ from the static and quasi-static CAs.
- •
The spreading (advancing) phase dominated by inertia forces.
- •
The CAs in the receding phase sensitive to surface wettability.
- •
No simple relationship between the classic CA hysteresis and the dynamic counterpart.
