固定偏角垂直轴潮流能水轮机叶片安装位置试验研究

Experimental study on blade preset position of fixed pitch vertical axis tidal turbine

叶片安装位置是影响固定偏角垂直轴潮流能水轮机水动力性能的关键参数之一,为了研究其对水轮机性能影响的基本规律,建立了垂直轴水轮机水槽模型试验系统,设计了垂直轴水轮机性能和载荷测试方法。通过试验结果的分析,得到了叶片安装位置对水轮机能量利用率、推力系数、侧向力系数和合力系数的影响规律,为水轮机设计提供了试验依据。

The blade preset position is one of the key parameters that affect the performance of the fixed pitch vertical axis tidal turbine.A model experiment was established to obtain the law that the performance of the turbine affected by the preset position of the blade,and a method for the measuring of the performance and the load of the turbine was designed too.After analyzing the experiment result,the relationship between the blade preset position and the energy efficiency,trust coefficient,lateral force coefficient and the total force coefficient was obtained,this provides a experimental evidence for the design of the turbine.
