摘　　要：该研究的主要目的是寻找一种新的模拟方法,尽量精细地模拟出大范围流场中潮流发电机与流场的相互作用。根据这一目标,提出一种耦合叶素模型的水平轴潮流发电机的表示方法,并将它集成到有限差分算法之中。利用集成后的模型,对实验室尺度的水轮机阵列实验进行模拟,并将模拟结果与实测数据进行对比。实验结果表明,该耦合模型可较好地模拟出水轮机阵列下游5倍直径以外的流场分布。A novel simulation method was searched to simulate the interaction between tidal turbines and flow field in a large area. A robust turbine model was proposed and then integrated into a finite difference method code. The improved model was used to simulate a flume experiment of tidal turbines in laboratory and comparisons were made between simulations and measurements. The results showed that the coupled model can predict correctly the flow field beyond approximate 5 diameters downstream of the rotors.
