摘要：

The accumulation of 5 mm large-scale mosquito corpses on the wind blade affects the overall aerodynamic performance of wind turbine. In order to investigate this problem, the aerodynamic performance of wind blade covered with different scales roughness in chord-wise was simulated by using SST k-ω turbulence model. The numerical research was carried out on the NERL Phase VI wind turbine. The results show that the roughness greatly impacts on the performance of the wind turbine, i.e. increasing roughness results in the significant efficiency decrease. In addition, the roughness attribute to a small low pressure vortex in the negative pressure surface of region near the blade tip, and also advance the transition. This effect is more obvious under the condition of the larger scale roughness, and the intensity of the wake vortex will be greater. Adding roughness at 75%c on the pressure surface of the blade will generate the greatest pneumatic loss to the airfoil. © 2022, Solar Energy Periodical Office Co., Ltd. All right reserved.
