沿着风能产业的蓬勃发展,海上漂浮式风力发电机引起了学术界和企业界的广泛关注。本文利用开源CFD框架OpenFOAM研究了支撑平台运动对漂浮式风力涡轮机空气动力学特性的影响。平台运动响应,包括纵荡、升沉和俯仰,叠加到风力涡轮机的旋转上。比较分析了不同平台运动方式下风力机涡轮机的推力和扭矩以及流场。结果表明,移动的支撑平台可以有很大的影响,浮动海上风力涡轮机,因此需要在设计过程中仔细考虑。
Along with the flourishing of the wind energy industry, floating offshore wind turbines have aroused much interest among the academia as well as enterprises. In this paper, the effects of the supporting platform motion on the aerodynamics of a floating wind turbine are studied using the open source CFD framework OpenFOAM. The platform motion responses, including surge, heave and pitch, are superimposed onto the rotation of the wind turbine. Thrust and torque on the wind turbine are compared and analysed for the cases of different platform motion patterns together with the flow field. It is shown that the movement of the supporting platform can have large influences on a floating offshore wind turbine and thus needs to be considered carefully during the design process.
