LEADING ENGINEERING SIMULATION CONFERENCE
The engineering problem is the estimation of the ice mass on an aircraft during critical flight conditions. The study has been focused on the ice accretion phenomenon on an airfoil in different weather conditions involving different ice shapes and different aerodynamics impacts.
The principal objective is to reproduce the rime ice accretion during long exposure time. The results will be compared with a complete nasa database and with a 2D ice code to validate the simulations results. Once this first problem solved, the two others icing type (mixed and glaze) have been studied. This work has been firstly done on a 2D airfoil corresponding to a global regional transport aircraft and then on a 3d swept wing with a glc-305 airfoil section. This problem has been solved thanks to a specific strategy of meshing and with an adjusted numerical methodology.
The benefit of this study is to have a methodology validated and ready to be applied on industrial cases in the context of certification for example.
