摘　　要：近些年,浮式风力机已经进入了小规模实尺度试验及商业运营阶段,然而对浮式风力机的试验及数值模拟研究还不够充分。文章结合荷兰海洋研究所(MARIN)海洋水池的风浪联合模型试验结果,将一种三立柱半潜型浮式风力机与固定式风力机的气动性能进行了对比研究。经模型试验研究发现:在风力机的水池试验中,缩尺模型的推力系数较理想,但难以获得较好的能效系数;在相似试验条件下,相较于固定式风力机,浮式风力机叶轮受到的气动推力稍大。In recent years,the floating offshore wind turbines(FOWTs)have entered a phase of realscale sea tests and commercial operations.However,there is still a lack of experimental and numerical simulation.Combined with the results of model test in Maritime Research Institute(MARIN),a contrastive study on the aerodynamic performances between a semi-submersible FOWT and a fixed bottom wind turbine will be carried out in this paper.It is found in the model test that the thrust coefficient of scaled turbine model is relatively ideal while it is difficult to obtain a good power coefficient.Under the similar experimental conditions,the aerodynamic thrust of turbines in the FOWT is slightly larger than that in the fixed wind turbines.
