摘要
应用竖轴水轮机阵列水动力性能预报程序研究潮流能水轮机阵列水动力干扰现象。分析单体的相对旋转方向对其自身水动力响应以及对阵列整体获能效率的影响方式、影响程度和影响规律。研究表明:反向旋转水轮机组整体获能效率明显比同向旋转对应值高,水轮机间距越小,反向旋转的优势越明显。和同向旋转相比,反向旋转转子力矩系数均值大,对应的峰值高。较之于同向旋转情况,反向旋转情况下水轮机叶片合力均值略大。
In this paper,the hydrodynamic interference characteristics of the turbine array were studied by using the program for predicting the hydrodynamic performance of a vertical axis turbine array. The influence of the rotation direction on the hydrodynamic response of the turbine and the influence on the overall energy efficiency of the array were analyzed. The results show that the overall energy efficiency of the reverse rotating turbine is higher than that of the same direction rotation,and the smaller the turbine spacing,the more obvious the advantage of the reverse rotation. Compared with the same direction rotation,the torque coefficient of the reverse rotating rotor is large and the peak value is higher.Also the water turbine blade force value is slightly larger.
