摘要：

With the help of Stokes number of particle, the erosion behavior of wind turbine blade was studied by analysing the process of sand impact with its airfoil. It is found that the sands will bypass the blade and no erosion formed when the Stokes number of particle is smaller than a certain value. With the increase of the Stokes number of particle, the sands begin to impact the blade and erode it, and the erosion area will expand gradually from blade leading edge to entire pressure surface. The most serious erosion must be located at the two sides of the stagnation point.
