What role do capillary forces play in aircraft icing? 💧✈️
➡️My PhD research investigates how water moves and freezes inside cold surface grooves.
❄️ By combining capillary flow and heat-transfer modeling, my work aims to:
- Understand how surface geometry and temperature gradients influence liquid transport
- Predict freezing behavior and improve existing icing prediction models
- Support the development of safer and more efficient anti-/de-icing solutions
To experimentally investigate and to develop a theoretical model for solidification and for a capillarity driven liquid flow in a cold groove as typically encountered on structured or rough solid or ice substrates
- Study of the flow propagation and freezing in liquid rivulet in a single groove
- Rivulet flow in two intersecting grooves
Design and virtual certification of a hybrid ice mitigation system (PWG2)
