本文采用准定常切片理论对一种独特的30 kW对转涡轮机系统的气动性能进行了研究。利用缩尺模型转子的风洞试验数据，在涡轮机系统的性能分析中考虑了位于主转子上风处的辅助转子的近尾迹特性。利用动量理论结合实验尾流模型，研究了两旋翼的相对尺寸和最佳位置。此外，性能预测结果沿着与全尺寸的现场测试数据获得的C/R风力涡轮机系统与传统的单转子系统进行了比较，并证明了当前的C/R涡轮机系统的有效性。
In the present work, the aerodynamic performance prediction of a unique 30kW counter-rotating (C/R) wind turbine system, which consists of the main rotor and the auxiliary rotor, has been investigated by using the quasi-steady strip theory. The near wake behavior of the auxiliary rotor that is located upwind of the main rotor is taken into consideration in the performance analysis of the turbine system by using the wind tunnel test data obtained for scaled model rotors. The relative size and the optimum placement of the two rotors are investigated through use of the momentum theory combined with the experimental wake model. In addition, the performance prediction results along with the full-scale field test data obtained for C/R wind turbine system are compared with those of the conventional single rotor system and demonstrated the effectiveness of the current C/R turbine system.
