Did you know ice build-up on aircraft wings can dramatically change airflow?❄️🧊✈️
When ice forms, smooth (laminar) airflow may turn turbulent, increasing drag and reducing efficiency.
🎓 In his PhD research, Michele is investigating laminar-turbulent transition when ice is present, using wind tunnel experiments and numerical simulations. By studying the rough surface created by ice🧊〰 ❄️, the goal is to improve predictions and design safer, more efficient aircraft.
To investigate the effects of ice roughness experimentally and numerically on laminar-turbulent transition and characterize ice structures transitional region.
- Experimentally characterize the transitional region in order to develop models on the extent of this region and on the intermittency. Investigate the correlation between these parameters and the roughness characteristics
- The experimental model and the measurement methods will be adapted from recent works in ONERA regarding roughness. The investigated rough surfaces will be derived from real ice characterization
Detection of ice conditions and real-time power control of IPS (PWG1)
