The icing of aircraft on the ground is an important flight safety issue. Aircraft must be de-iced and anti-iced to remove and protect the aircraft from freezing and frozen contamination, respectively, before and during takeoff. Winter de-icing and an

During winter, aircraft de-icing and anti-icing is a significant part of the operations at large airports. These mandatory operations ensure that the aircraft is clean of any contaminations during take-off. However, these operations are complex due t

Successful icing/de-icing simulations for rotorcraft require a good prediction of the convective heat transfer on the blade’s surface. Rotorcraft icing is an unwanted phenomenon that is known to cause flight cancelations, loss of rotor performance
