摘要	This is the result of the continuous exposure of wind turbines to the elements and of particularly high rotor blade tip speeds, which exceed a velocity of 90 m/s. These effects result in the surface of wind turbines will be worn and create rough and pock marked leading edge surfaces. In order to research on the effects of leading edge erosion on the aerodynamic characteristics of airfoil, the full two-dimensional Navier-Stokes equations and the SST k-ω turbulence model were used to investigate incompressible viscous flow past the wind turbine two-dimensional airfoils with different erosion heights and thicknesses. Results showed that the leading edge erosion will change theaerodynamics shape of the airfoil and cause an increase of drag and decrease of lift for the airfoil. The erosion thickness had a little influence on the aerodynamics of the airfoil when the erosion height was less than 0.5% of the chord length, it will be serious when the erosion heights were greater than 1.0%c. The lift coefficients will have no big change when the erosion height reached a certain extent, which is 1.0%, 2.0% and 3.0% for airfoils with a 12%, 18% and 25% erosion thickness, respectively. The pressure coefficients distribution curves of the eroded airfoils overlapped each other when the erosion height reached that certain value. © 2017, Editorial Board of Acta Energiae Solaris Sinica.
