一台20千瓦的原型浮动电流涡轮机被设计用于在黑潮中运行，黑潮以大约1.5米/秒的最大速度通过台湾东海岸。黑潮的位置和速度大致一致，为台湾提供了稳定和安全的能源。搭建了一台800-W 1/5比例模型的试验装置，对所设计的涡轮进行了转速、推力和扭矩的测量。该装置在拖曳槽中以恒速进行了测试。利用电子制动器模拟发电机产生的转矩来控制涡轮机的旋转。根据实测数据计算了功率系数、扭矩系数和推力系数。确定了这三个系数与叶尖速比的关系。实测的功率系数和扭矩系数与计算结果吻合较好。实测推力系数大于计算推力系数。本文讨论了测量推力系数偏高的可能原因。
A 20KW prototype floating current turbine was designed for operating in the Kuroshio Current, passes along the eastern coast of Taiwan at a maximum speed of approximately 1.5m/s. The location and speed of the Kuroshio Current are generally consistent, offering Taiwan a stable and secure energy source. A test apparatus, which included a 800-W 1/5 scale model of the proposed turbine, was prepared to measure the rotation, thrust and torque of the designed turbine. The apparatus was tested in a towing tank at constant speed. The rotation of the turbine was controlled using an electronic brake to simulate the torque induced by the generator. The power coefficient, torque coefficient and thrust coefficient were calculated from the measured data. The relationships of these three coefficients with tip speed ratio were determined. The measured power coefficient and torque coefficient agreed well with the calculated results. Whereas the measured thrust coefficient was higher than that calculated. The likely cause of the high measured thrust coefficient is discussed in this paper.
