摘要：
The unsteady hydrodynamic characteristics of vertical axis tidal turbine are investigated by numerical simulation based on viscous CFD method.The starting mechanism of the turbine is revealed through analyzing the interaction of its motion and dynamics during starting process.The operating hydrodynamic characteristics of the turbine in wave-current condition are also explored by combining with the linear wave theory.According to possible magnification of the cyclic loads in the maximum power tracking control of vertical axis turbine,a novel torque control strategy is put forward,which can improve the structural characteristics significantly without effecting energy efficiency.
