| 摘 要： | 提出了一种新型海洋潮流能获取装置--潮流能柔性叶片水轮机.其叶片采用柔性材料,可适应流体发生形变,从而它能自动调节攻角,能充分利用流体的升力效应和阻力效应做功,具有独特的水动力学特性.以柔性叶片水轮机获能系数(Cp)为主要研究目标,通过水槽模型实验对其影响因素进行了研究.实验证实了该柔性叶片水轮机的独特水动力学特性,而且证明,叶片形状和水轮机结构形式是其性能的主要影响因素,并通过分析得到了具有较佳水动力学特性的水轮机的叶片形状和水轮机结构形式.

| Abstract: | The paper puts forward a new type of marine current energy conversion device,a flexible vane turbine.Its flexible vane is made of flexible material,which can deform to adapt to fluid.Thus the turbine can adjust the attack angle auto- matically to take full advantage of the lift effect and drag effect and produce as more power as possible,so it has unique hydrodynamic performances.Focusing on the power efficiency coefficient (C_p),the authors studied its hydrodynamic characteristics and the affecting factors... |
