Abstract:

In order to investigate the aerodynamic characteristics of Wind turbine tower under rated operating conditions, a 1:1 numerical model of 1.5MW wind turbine was established using UG finite element modeling software, and the velocity field and pressure field distribution of wind turbine with cross-sections of r / R = 20%, r / R =40%, r / R =60%, r / R =80%, r / R =120% and r / R =140% were analyzed. The results show that with the increase of r / R, the backflow and vortex on the leeward side of the tower are produced to different degrees, and the vortex separation point is shifted backward. With the increase of r / R, the pressure value and range about 0° symmetry axis gradually become smaller, and the pressure values on both sides of the tower show negative pressure and symmetric distribution, and the tail flow area of the tower gradually returns to the inlet pressure.
