摘　　要：在强沙尘暴天气条件下,风电机组仍然需要处于正常工作状态,而沙尘颗粒对风机的性能和使用寿命会产生严重的影响。使用1.5 MW的风力机叶片模型作为仿真模拟的对象,使用FLUENT软件中的SST k-ω湍流模型和离散相(DPM)模型研究了不同沙尘颗粒对风机气动特性的影响,为风力机工程设计与分析提供参考。Wind turbines need to be in normal working condition under strong sandstorm weather conditions,and dust particles will have a serious impact on the performance and service life of wind turbines.A 1.5MW wind turbine blade model is used as the simulation object,and the SST k-ωturbulence model and discrete phase(DPM)model in FLUENT software are used to study the influence of different dust particles on the aerodynamic characteristics of wind turbines,which provides reference for the design and analysis of wind turbine engineering.
