摘要：
In order to study the effect of hydrodynamic performance on vertical axis tidal turbines, the ANSYS-CFX software was used to simulate the yawing motion of two blade vertical axis turbines. Besides, the influence of yawing on energy utilization of the turbine was studied, the thrust coefficient and lateral force coefficient time history curves also were analyzed under different frequency and different speed ratios, and the method of least squares was used to analyze the load of turbines. The results show that compared with turbine only rotating in uniform stream, yawing motions have little influence on energy utilization of the turbine, but it has a great impact on the instantaneous fluctuation amplitude of thrust and lateral force. As the speed ratio and yawing frequency increase, the instantaneous fluctuation amplitude increases, too. The damping coefficient of thrust and lateral force is related to speed ratio but has nothing to do with yawing frequency. Besides, the speed ratio increases, the damping coefficient increases. The results can provide reference for the design of floating tidal power stations. © 2016, Editorial Board of Journal of Shanghai Jiao Tong University. All right reserved.
