What are rivulets? 🌊❄️
Thin water films on airplane wings break into small streams called rivulets. These rivulets freeze, creating icy surfaces that change the wing’s aerodynamics!
➡️ Hani Mina’s PhD work focuses on understanding and preventing these risks. ✈️👨🔬
To experimentally investigate the dynamics and thickness of liquid films at low temperatures and improve predictions of liquid films transition into rivulets
- To predict the transition of the water film into rivulets on a rigid surface and which rivulet pattern is adopted
- Test different experimental approaches as fast imagery and LED Induced Fluorescence to analyze water film transition into rivulets
- Investigate water film thickness by a resistive method
