Abstract

In order to explore the effect of forced pitch motion on the hydrodynamic performance of the floating tidal current turbine, a CFD numerical model of rotation and pitch coupling motion of the floating tidal current turbine is established based on the combination method of improved delayed detached eddy simulation（IDDES） and sliding mesh technology. Firstly, the flume test results of the tidal current turbine are selected to validate the calculation accuracy of the established numerical model. Secondly, the three-dimensional unsteady simulation of the floating tidal current turbine is carried out under different pitch frequencies and pitch amplitudes. The research results show that：1）The overall fluctuation frequency of the hydrodynamic coefficient（energy utilization coefficient and axial load coefficient） of the turbine is twice the pitch frequency, accompanied by the high-frequency pulsation whose frequency is the rotation frequency of the rotor;2）With the increase of pitch frequency, the average hydrodynamic coefficient increases slightly, while with the increase of pitch amplitude, the average hydrodynamic coefficient decreases slightly, but they are less than the average hydrodynamic coefficient without pitch motion;3）At the position of the maximum pitch amplitude, the upstream surface of the turbine blade bears different degrees of hydraulic load. The pitch motion has an effect on the wake at the equilibrium position and the maximum amplitude position, and the wake has a relatively apparent low-speed swing phenomenon.
