Title: Flow field and aerodynamic performance of wind turbine in complex terrain
Abstract: In order to study the motion characteristics of flow field and related aerodynamic performance for complex mountain wind turbine, based on wind speed and topographic data, using pro/E and Gambit software, the models of XE93 2000 type wind turbine and complex mountain flow field were built. Using fluent software, the external flow field and aerodynamic performance of horizontal axis wind turbine were analyzed. The results show that due to small wind shear, the large-scale wind turbine is particularly suitable to be installed on the mountain top within the height range of60 200 m, in addition, the ridge tangent to the main wind direction is also a good installation site for wind turbine.Airflow speed drops after the wind turbine and the recovery process is long, wind speed in 500 m scope after wind turbine is still affected. Wind load on the tower accounts for about 15.6% of the total wind load of wind turbine, driving moment and drag force are the main aerodynamic loads of wind wheel, and their values increase with the increase of wind speed significantly.
