Analysis on Effects of Coating Material Properties on Water Droplets Impacting Wind Turbine Blades at High Velocity
摘要
Abstract
The wind turbine blades are susceptible to erosion during operation due to repeated impacts from raindrops.Ero-sion damage can affect the aerodynamic and structural performances of the blade,leading to a reduction in annual energy produc-tion and an increase at maintenance costs.Therefore,a fluid-solid coupled model is developed to simulate the vertical impact of a single water droplet of 2 mm in diameter with a velocity of 100 m/s on coating systems with different surface coating and to ana-lyze the effects of material properties on the impacts.The results show that the larger the Young'smodulus of the coating materi-al,the shorter the initial compression phase of the water droplets will be.When Young'smodulus of the coating material increas-es,the water droplets'impact leads to an increase in the stress level in the material and more pronounced surface Rayleigh waves.As a result,materials with low Young'smodulus respond to impacts better,which reduces stresses on the impacted sur-face and suppressing stress waves.The results of this study can provide guidance for the development of wind turbine blade sur-face coatings that are more resistant to repeated impacts by high-velocity water droplets.关键词
