Abstract

Flowfield simulation and aerodynamic performance analysis of complex iced aerofoil are conducted with hybrid multi-block grid technique. To overcome the difficulty of generating structure grid on complex geometry, a point-to-point hybrid grid generation method is developed in this paper. An unstructured grid is imposed in the zone near the iced aerofoil to handle the complicated iced geometry. A structure grid is imposed in the zone wrapping the unstructured grid to save the storage and computational time. The implementation of point-to-point hybrid grid simplifies the flux construction at the interface between two types of grid. The Reynolds-averaged Navier—Stokes equations are solved with implementation of the shear-stress transport two-equation turbulence model in both types of grid. As a comparison, the numerical simulation results with Spalart—Allmaras turbulence model are also presented. The results of numerical simulation on iced aerofoil validate the method developed in this paper and show that ice accretion has serious effect on aerodynamic performance of aerofoil.
