摘　　要：以柔性叶片水轮机获能区的研究为重点,分析柔性叶片水轮机的受力特性,提出正负获能区的概念,明确获能区的分布情况,在此基础上提出一种通过减小负获能区的不利影响来提高柔性叶片水轮机整体获能能力的方法,并利用数值模拟和水槽模型实验进行分析和验证。最后根据柔性叶片水轮机获能区的特点,针对不同的环境条件提出相关工程应用方案。Flexible blade turbine is a kind of novel device used in tidal stream energy conversion. The concept of the negative power region was proposed in the paper. By establishing mathematical model and numerical simula- tion, a method of improving the overall power generation capacity by changing the occlusion degree was put forward and the method was verified by numerical simulation and flume experiment. The result showed that flexible blade turbine could increase the overall power efficiency under the condition of shielding the negative power region, which proved that changing the occlusion degree could be a method of improving the power converting capability of flexible blade turbine.
