Atmospheric icing can cause up to 16% of weather-related aircraft accidents. Ice accretions on an aircraft lead to a decrease of the aerodynamic performance and can obstruct critical sensors. Predicting the ice accretion location and shape can allow to efficiently fight against it. During the past two decades, numerical simulation of aircraft icing became a powerful complementary tool to experimental measurements. Most of the icing codes rely on the coupling between the air solution provided by CFD, a droplet solver to estimate the impingement on the geometry, and an ice accretion solver. The ice accretion solver often uses the Messinger approaches to compute the ice growth, but other numerical methods have emerged, such as the shallow water icing model (SWIM). The objective of the paper is to extend the capabilities of the open-source SU2 CFD software to ice accretion simulations by implementing the SWIM model and to verify the rime ice shape predictions. After a presentation of the model equations and implementation, the 3D results of ice accretion for the test cases NASA27 and NASA28 around a NACA0012 wing will be shown and compared to existing literature.
