摘　　要：为确保涡轮机的长期可靠性,在设计潮流涡轮机时应考虑海浪条件。使用直径为0.9 m的三叶片水平轴潮流涡轮机(Horizontal Axis Tidal Stream Turbine,HATST)作为基准模型,采用计算流体动力学(Computational Fluid Dynamics,CFD)开源软件OpenFOAM预测HATST在海浪和水流条件下的性能。对其进行网格依赖性测试以选择最佳网格数,捕捉流动特征。将生成的波浪轮廓与三阶Stokes波浪理论结果进行比较,发现模拟结果与理论结果一致。研究不同波频和波幅对HATST功率性能的影响,结果表明,波幅对功率性能的影响较为明显,波频的影响相对较小。In order to ensure the long-term reliability of the turbine,the wave conditions should be considered when designing the tidal turbine.A three-bladed Horizontal Axis Tidal Stream Turbine(HATST)with a diameter of 0.9 m is used as the benchmark model,and the open source Computational Fluid Dynamics(CFD)library OpenFOAM is used to predict the performance of HATST under wave and current conditions.The grid dependence tests are conducted to select the optimal grid number to capture the flow characteristics.As a verification study,the generated wave profile is compared with the results obtained from third-order Stokes wave theory,and it is found that the simulation results are consistent with the theoretical results.The effects of different wave frequencies and heights on the power performance of HATST are studied,and the results indicate that the wave height is of more significant impact on the power performance.
