摘　　要：近年来,配有固定导流叶片的冲击式透平在OWC式波能发电装置的应用中受到广泛重视。利用Fluent软件对这种透平进行三维数值模拟,考察了外径间隙和轮毂比对透平工作性能的影响;研究了动叶片表面的压力分布和空气流动情况。计算结果与试验数据较为符合,为透平的设计提供了参考值,该数值方法可以成为深入研究波能发电装置冲击式透平的有效手段。In recent years,impulse type turbines provided with fixed guide blades have received widespread attention when used in OWC ( Ocean Wave Converter) type wave-energy power-generation plants. A three-dimensional numerical simulation has been performed of this kind of turbines by using software Fluent,and the influence of the ratio between the outer-diameter clearance and the hub on the operation performance of the turbines,investigated. In addition,the pressure distribution and air-flow conditions on the surface of rotating blades were also studied.The calculation results are in relatively good agree-ment with test data,thus providing a valuable reference for the turbine design. The numerical simulation method in ques-tion can become an effective means for an in-depth study of the impulse type turbines for use in wave-energy power gener-ation plants.
