| Abstract | NRC has developed an original, three-dimensional icing modelling capability, called the “morphogenetic” approach, based on a discrete formulation and simulation of ice formation physics. Morphogenetic icing modelling improves on existing ice accretion models in that it is capable of predicting simultaneous rime and glaze ice accretions and ice accretions with variable density and complex geometries. To partially validate the model, we have performed laboratory experiments of ice accretions on a NACA0012 swept wing in the NRC Altitude Icing Wind Tunnel (AIWT). Ice shapes were recorded and analysed for 30° and 45° sweep angles and for a range of airflow and icing conditions. The swept wing configuration was chosen because it is the most challenging case for all numerical predictive models. The objective of this paper is to compare model and experimental ice predictions on a swept wing, including complex three-dimensional features such as lobster tails. The results show that the morphogenetic approach can produce realistic simulations of both the overall size/shape and the detailed structure of the ice accretions forming on a swept wing. As far as we know, no other numerical icing model can simulate such three-dimensional ice structure complexity. |
