Did you know that ice roughness can affect a wing’s aerodynamic performance?❄️ 🛩️
🎓 Riccardo’s PhD project deals with the intriguing and complex problem of ice roughness 🧊〰️ ❄️. Within aircraft icing, which may represent a serious hazard for an airplane in flight, ice roughness could play a major role in affecting the physics of the airflow✈️.
Think of it as a surface pattern, very irregular, that can easily disturb the air close to the wing surface and determine changes in friction and heat exchange.
🎯Riccardo’s work targets such issue using accurate numerical simulations performed on high-performance computers🖥️, in the attempt to enhance our understanding of the problem and improve our current predictions.
To perform direct numerical simulations to uncover the details of roughness onset due to ice accretion
- Perform LES and DNS simulation of two-phase flows to capture the onset of roughness due to ice formation
- Include in existing RANS turbulence models local effects resulting from simulations
