Abstract:

A point-to-point structure/unstructured hybrid grid generation method is developed in this paper to avoid the difficulty of generating structure grid on complex iced airfoil, and the corresponding analysis of aerodynamic performance is carried out. An unstructured grid is imposed in the zone near the iced airfoil to fit the complex boundary. A structure grid is imposed in the zone wrapping the unstructured grid to save the storage and computational time.
