In order to study the influence of high tidal current velocity on the dynamic characteristics of horizontal axis tidal turbine under free wave conditions, STAR-CCM+ was used to establish a numerical calculation method for the hydrodynamic characteristics of tidal energy turbines under sea wave conditions. The law of wave influence on the rotation of tidal energy turbines and the characteristics of wake flow generated during the rotation were obtained. The results show that the amplitude and frequency of the angular acceleration of the tidal energy turbine are affected by the waves, but the fluctuation amplitude is less than the wave amplitude, the variation frequency is higher than the wave frequency. The wake flow produced by the rotation of the hydraulic turbine will make the flow field around the next hydraulic turbine more chaotic, and will have an impact on the blade rotation, turbine shaft load and energy utilization efficiency. Based on the analysis of the changing trend of pressure fluctuation, it is considered that the wake flow has little effect on the fatigue damage of hydraulic turbine.

为了研究自由海浪条件下的高潮汐流速对水平轴潮流能水轮机的动态特性影响,基于STAR-CCM+建立了海浪条件下潮流能水轮机水动力特性的数值模拟方法,得到了海浪对潮流能水轮机转动影响规律及转动过程中产生的尾流特征。结果表明,潮流能水轮机角加速度的幅度与频率受海浪影响,但波动幅度小于海浪波动幅度、变化频率高于海浪波动频率;水轮机转动产生的尾流会使下一个水轮机的周围流场更紊乱,对叶片转动的影响、水轮机轴负载和能量利用率等方面会产生影响;压力脉动变化趋势分析认为,尾流对水轮机疲劳损伤并无太大影响。

为了研究自由海浪条件下的高潮汐流速对水平轴潮流能水轮机的动态特性影响,基于STAR-CCM+建立了海浪条件下潮流能水轮机水动力特性的数值模拟方法,得到了海浪对潮流能水轮机转动影响规律及转动过程中产生的尾流特征。结果表明,潮流能水轮机角加速度的幅度与频率受海浪影响,但波动幅度小于海浪波动幅度、变化频率高于海浪波动频率;水轮机转动产生的尾流会使下一个水轮机的周围流场更紊乱,对叶片转动的影响、水轮机轴负载和能量利用率等方面会产生影响;压力脉动变化趋势分析认为,尾流对水轮机疲劳损伤并无太大影响。

In order to study the influence of high tidal current velocity on the dynamic characteristics of horizontal axis tidal turbine under free wave conditions, STAR-CCM+ was used to establish a numerical calculation method for the hydrodynamic characteristics of tidal energy turbines under sea wave conditions. The law of wave influence on the rotation of tidal energy turbines and the characteristics of wake flow generated during the rotation were obtained. The results show that the amplitude and frequency of the angular acceleration of the tidal energy turbine are affected by the waves, but the fluctuation amplitude is less than the wave amplitude, the variation frequency is higher than the wave frequency. The wake flow produced by the rotation of the hydraulic turbine will make the flow field around the next hydraulic turbine more chaotic, and will have an impact on the blade rotation, turbine shaft load and energy utilization efficiency. Based on the analysis of the changing trend of pressure fluctuation, it is considered that the wake flow has little effect on the fatigue damage of hydraulic turbine.
