    Abstract:

    In order to improve the performance of the wind turbines, the problem that the wind turbine is affected by the building in actual operation is solved. Using the simulation analysis software Fluent, the aerodynamic performance of the new Nautilus equiangular spiral wind turbine with different numbers of blades is studied, and the torque characteristics and wind energy utilization of the wind turbine are analyzed. The layout model of buildings and wind turbines are established and the turbulence characteristics of buildings and compare the torque performance of wind turbines in the turbulent environment are analyzed. The results show: the overall performance of the three-blade wind turbine is more superior, and the tangential speed near the building is significantly increased. The performance of the new Nautilus equiangular spiral wind turbine near the building has been significantly improved and the feasibility of installing the Nautilus equiangular spiral wind turbine near the building is verified. 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.
