摘要
叶轮作为潮流能水轮机捕能的关键部件,其水动力性能以及结构性能会影响水轮机的捕能效果及其结构的安全性。本文以30 W的小型水平轴潮流能水轮机为例,分别基于单向流固耦合和双向流固耦合模型对在设计工况下的叶轮水动力性能与结构性能进行了稳态分析,对比研究了两种耦合模型所得到的叶轮捕能系数、叶轮表面压力分布等水动力性能和叶轮应力分布等结构性能,为进一步对叶轮结构优化提供参考依据。
As the key component of tidal current energy turbine, the hydrodynamic and structural performance of the turbine will have some effect on the turbine＇s energy-catching efficacy and its safety. In this paper, taking 30 W small horizontal axis tidal current energy turbine as an example, its hydrodynamic and struc-tural performances in designed working condition were analyzed based on one-way and double-way fluid-structure interaction modes, respectively. Then, the hydrodynamic performance, such as energy-catching coeffi-cient and pressure distribution on the surface, and its structural performance, such as the stress distribution,are compared and analyzed, which result from two kinds of couple modes. Finally all the results will be useful for the further optimal design of the turbine.
