摘　　要：以提高柔性叶片水轮机获能能力为目的,通过理论数值计算和试验分析,结合负获能区对柔性叶片水轮机的影响,对柔性叶片水轮机的导流罩形式进行研究。通过改变影响导流罩水动力学性能的几个重要参数,分别对柔性叶片导流罩进行水动力学数值模拟,得出水动力学特性较优的柔性叶片水轮机导流罩结构形式。In this paper, in order to improve efficiency of flexible blade turbine, a new type of diffuser was put forward based on consideration of the influence of negative energy capture area of flexible blade turbine and augmentation effect of the diffuser. Numerical simulations were performed by considering several parameters of diffusers. An optimized type of diffuser was obtained by discussing its hydrodynamic performance, drag forces and conflux effects.
