摘　　要：风沙环境中,沙尘会对风力机气动性能产生影响。基于欧拉双流体模型,研究来流风速10m/s的情况下,不同的沙粒体积分数、粒径对翼型du93,s802和s803升力的影响。结果表明:在一定范围内,随着沙粒的体积分数增大,叶片的升力大小呈线性增加,其中s803翼型增幅最明显,达到16.74%;du93翼型增幅最小,为14.62%;沙粒的粒径对叶片的升力影响微弱,可忽略不计;三种翼型中s803产生的升力最大,s802次之,du93气动性能最差。研究结果对风沙环境下,风力机翼型选取具有指导意义。In windy and sandy environments,sand and dust can have an impact on the aerodynamic performance of wind turbines.Based on the Euler dual fluid model,the influence of different sand volume fractions and particle sizes on the lift of airfoils du93,s802,and s803 under the condition of incoming wind speed of 10m/s.The results show that within a certain range,as the volume fraction of sand particles increases,the lift of the blade increases linearly,with the s803 airfoil showing the most significant increase,reaching 16.74%.The du93 airfoil has the smallest increase,at 14.62%.The influence of sand particle size on the lift of leaves is weak and negligible.Among the three airfoils,the s803 produces the highest lift,followed by the s802,and the du93 has the worst aerodynamic performance.The research results have guiding significance for the selection of wind turbine wing shapes in windy and sandy environments.
