Modeling In-Flight Ice Accretion Under Uncertain Conditions

What is it about?

In-flight ice accretion is a detrimental phenomenon leading to the aircraft performance degradation and posing a serious threat to safety. We quantify the sensitivity of the predicted ice shape to uncertain test conditions with a twofold objective. On one hand, the aim is to shed light on the physics by exposing the relative importance of the diverse uncertain inputs to the resulting ice shape. On the other hand, this paper is also meant to be an embryonic effort towards assessing the accuracy of numerical predictions against real observations.
