Outline
In this paper, in order to study the dynamics of the model turbine with driven motion at different yaw angle operating condition, a wind turbine model based on elasticity is established. Under the condition of turbulent flow, the driven motion state of the model wind turbine is realized with irregular rotation, and the wake distribution characteristics and energy characteristics of the wind turbine are studied. The results show that when the yaw angle is 0°, the wake of the driven wind turbine is obviously smaller than that of the fixed wind turbine, and the turbulent kinetic energy is greater than that of the fixed wind turbine because of the multifreedom rotational motion of the driven wind turbine. With the increase of yaw Angle, the distribution of wake and turbulent kinetic energy of wind turbine appears radial deviation, and the deviation direction is opposite to the direction of yaw Angle rotation, and the wake and turbulent kinetic energy decreases with the increase of yaw Angle. With the increase of yaw Angle, the average output power of forced and fixed wind turbines decreases, and the average output power of forced wind turbines is smaller than that of fixed wind turbines.
