CANICE-2D & -3D

(Full screen view)


Currently, atmospheric icing is one of the major concerns for the certification authorities as well as the aircraft manufacturers since it presents a major hazard to aircraft operating under natural icing conditions. Atmospheric icing also represents a major concern when installing wind turbines in cold climate. Ice accretion on the rotor blades can result in reduced power production and increased rotor loads, which may require stopping the turbine for safety reasons and to prevent damage to the turbine structure.


CANICE-2D & -3D uses an aerodynamic panel method to solve for the potential flow field which is then corrected for compressibility effects. The code uses Lagrangian tracking to determine droplet trajectories and impingement locations. The modified Messenger model is used for ice accretion thermodynamics, in conjunction with an integral boundary-layer solution for heat and mass transfer rates. The code includes roughness, runback and water splash/ice shed models based on water-bead model.


The code has the capability of simulating super cooled large droplet conditions. The ice accretion is re-paneled and the airflow field is re-computed at each time step to determine the growth of the ice accretion as time proceeds. The code has also a module for the computation of the effects of a hot-air based anti-icing system.


Invited paper, as code developer at the NATO/RTO Workshop at CIRA, in Italy, on Assessment of Icing Code Prediction Capabilities. CANICE is one of the five major icing simulation codes in the world. It has been approved by Transport Canada to be used for the certification of Bombardier aircraft in icing conditions.
