摘要(Abstract)：
【目的】为解决传统水轮机在数值仿真时计算量大、耗时长等问题，采用致动盘（actuator disc）方法研究潮汐能水轮机尾流场及其水动力性能。【方法】将推力T作为体积力的附加源项形式均匀加载致动盘上，并应用OpenFOAM软件进行数值模拟，以捕捉潮汐能水轮机流场特性。【结果与结论】将实验数据与仿真结果对比，发现两者在推力系数和功率系数随尖端速度比（tip-speed ratio,TSR）的变化趋势一致。TSR=5.5时发现实验数据与仿真结果的湍流强度和速度高度吻合，两者在流场的中心截面上误差分别为3%与5%。致动盘模型展示在尾流场细节特征的捕捉优势，可为后续研究提供参考。
