摘要：

Modeling the 3D unsteady flow around the poles of wind turbines is an unusual mathematical problem. On the upper part of the pole the inlet flow is unsteady due to the wakes of the blades, and on the lower part the conventional flow around circular cylinders may be assumed. In this paper the velocity and pressure distribution, the frequency of the shedding vortices, the lift and drag coefficients are computed with rational simple assumptions using the FLUENT software, and Large Eddy Simulation (LES) is applied. The Fast Fourier Transform (FFT) of the lift coefficient gave new interesting results.
