  • To classify smoothly the complex structured grid,the aerodynamic performance of complex iced airfoil with hybrid multi-block grid was analyzed and calculated.An unstructured grid was applied to the zone near the iced airfoil,whereas a structured grid was applied to save the storage and computational time.The flux restructuring was simplified through point-to-point connection between different grids.The Reynolds-averaged N-S equations are solved using SST turbulence models the entire flow area.The results of numerical simulation show that structured/unstructured hybrid multi-block grid is feasible for calculating the aerodynamic performance of complex ice accretion,given the fact that ice accretion has serious influence upon aerodynamic performance of airfoil.
