2. Icing modeling: ice shape calculation codes
Modelling is carried out using four successive calculation codes:
the first determines the aerodynamic field around the profile ;
from this field, the second calculates the trajectories of the water droplets, assuming that they are subject only to drag forces due to the difference in speed between the droplets and the surrounding air. This calculation yields the tangent trajectories on the lower and upper surface, giving the zone where the ice can settle, and thus the dimensions of the protection system. The local intensity of capture on the profile is obtained by writing the conservation of droplet flow in a tube defined by two adjacent trajectories;
the third code used gives the value of the heat exchange coefficient using a boundary layer calculation that takes into account...
