文章摘要: Taking the S818 airfoil of 1.5MW wind turbine blade as the research object. Model of the finite element of airfoil flow field was built in this paper. The non-viscous incompressible Navier-stokes equations are used as flow control equation, which conducted numerical simulation analysis on Ice-free airfoil, airfoil of rime ice, chord-length ice, and horn ice. The pressure distribution are obtained from the lift-drag ratio, velocity vector and surface pressure of different thickness of the blade airfoil in the angle of attack from -2o to 20o.The results showed that the thicker of the ice coating, the shaper maximum lift-drag ratio of airfoil are decreased. Moreover, certain thickness of chord length ice and horn ice leads to the mutation of the loss of lift-drag ratio. When ice thickness is 10 mm, the maximum lift-drag ratio amplitude reduction of horn ice reached the maximum at 22.04%, the chord length ice at 11.97% and rime ice at 6.14%. In addition, the airfoil after icing would ente
