In the framework of HAIC European project, a capability for modeling glaciated and mixed-phase ice accretion has been added to IGLOO2D, the new ONERA 2D icing suite. A first set of models has been introduced for taking into account physical phenomena which are generally not considered for classical icing conditions: particle shape influence on the drag force, heat exchange between air and particles, melting and evaporation phenomena, complex particle interactions with dry and wetted walls, liquid film dynamics, influence of ice crystals on energy balance … To assess this new capability, test cases have been performed for mixed-phase ice accretion using results from the NASA-NRC experimental database 3,4 .
