摘要：

水平轴潮流能水轮机作为目前技术最成熟的潮流能获能装置，其水动力性能关系到整个潮流能量的转换效率。为提高潮流能的转换效率，对水轮机设计一种“M”型导流罩，基于Helicopter Multi-Block 3方法优化导流罩入口的开口角度，结合Fluent仿真软件探讨不同导流罩入口角度对水轮机水动力的影响。结果表明，加导流罩后水轮机水动力性能有明显提升，并且在导流罩入口角度为22.5°时水轮机水动力性能最佳，此时水轮机能量利用系数也较裸机的能量利用系数增大10%。

Abstract: As the most mature tidal turbine, the hydrodynamic performance of the horizontal axis tidal turbine is related to the conversion efficiency of the tidal. In order to improve the conversion efficiency of tidal, an ‘M’ type duct is designed, and based on the Helicopter Multi-Block 3 method to optimise the opening angle of different duct inlets, the influence of different duct inlet angles on the hydrodynamic performance of the turbine is investigated with the combination of Fluent simulation software. The results show that the hydrodynamic performance of the turbine is significantly improved after the addition of the duct, and the turbine hydrodynamic performance is best when the duct inlet angle is 22.5°, and the power coefficient at this time is also about 10% larger than that of the bare turbine.
