| 中文摘要: |
| 為了提高風力機組的整體性能，解決風力機在實際運行中受建筑物影響的問題，利用仿真分析軟件Fluent對不同葉片數的新型鸚鵡螺等角螺線型風力機進行氣動性能研究，建立建筑物與風力機組排布模型，分析建筑物擾流特性，對比擾流環境對風力機組轉矩性能的影響。結果表明：3個葉片風力機的整體性能更優；建筑物下游出現紊流區域，切向速度明顯增加，其附近的新型鸚鵡螺等角螺線型風力機組轉矩性能明顯提升，驗證了建筑物附近安裝鸚鵡螺等角螺線型風力機組的可行性。所提風力機組排布方式可有效提升風力機性能，為風力機結構優化設計和建筑物附近風力機排布提供參考。 |
| 英文摘要: |
| In order to improve the overall performance of wind turbines and solve the problem that the wind turbine is affected by the building in actual operation, the simulation analysis software Fluent was used to study the aerodynamic performance of the new Nautilus equiangular spiral wind turbine with different numbers of blades. The layout model of buildings and wind turbines were established, the turbulence characteristics of buildings were analyzed, and the torque performance of wind turbines in the turbulent environment were compared. The results show that the overall performance of the three-blade wind turbine is more superior; there is turbulence area at the lower position of the building, and the tangential speed is significantly increased; the performance of the new Nautilus equiangular spiral wind turbine near the building are significantly improved, which verifies the feasibility of installing the Nautilus equiangular spiral wind turbine near the building. The proposed arrangement of wind turbines can effectively improve the performance of wind turbines, and provide references for the optimal design of wind turbine structures and the arrangement of wind turbines near buildings. |
