摘要采用URANS方法数值计算了具有两个自由度三维刚性水翼的流致振动和声辐射问题,三维刚性水翼的振动是通过解刚性体的运动方程的方式实现，流场在Fluent里用k-ω SST湍流模型计算。首先，进行了网格无关性验证和时间步长的验证，并和相关的实验结果以及Theodorsen非定常理论的结果进行了对比，计算结果具有较高的吻合度。然后重点计算了质量静矩和质量惯性矩对振动以及振动临界状态的影响，并且计算了不同振动状态下的声辐射问题。计算结果表明，质量静矩和质量惯性矩对水翼的振动有较大的影响，而水翼的振动会使噪声大幅增加。

Abstract：The flow-induced vibration and sound radiation problem of three-dimensional hydrofoil with two-degree of freedom (2DOF) was studied in this paper with the URANS method.The hydrofoil’s vibration was implemented with calculating the hydrofoil’s motion equations,the flow field was calculated with the k-ω SST turbulence model.First of all,the mesh independent verification and time step verification were carried out.The method was validated by comparing the simulation results with that of experiment and the Theodorsen’s theory,which shows quantitatively agreement.Furthermore,the impact of mass moment and moment of inertia to the vibration and the sound radiation problems were calculated.The calculation results show that the effects of mass moment and moment of inertia to the vibration of hydrofoil are significant,and the hydrofoil’s vibration will increase the noise.
