中文摘要:
      针对仿金枪鱼尾鳍,开展了摇摆幅度对其推进性能影响的研究。首先,基于浸入边界法实现对尾鳍数值模拟,通过与试验比对验证数值方法的有效性。然后,建立仿金枪鱼尾鳍的三维模型,数值模拟其不同摇摆幅度下推进性能的变化。最后,对仿真结果进行对比分析。结果表明,在大摇摆幅度下,随着摇摆幅度增大, 尾鳍受到平均推力系数缓慢增大, 推进效率快速下降。研究可为仿金枪鱼尾鳍类机器的设计和控制提供参考和指导。
英文摘要:
      The influence of the swing amplitude on tuna-like caudal fin’s propulsion performance was carried out. Firstly, numerical simulation of caudal fins was carried out based on the immersion boundary method. The validity of the numerical method was verified by comparison with experiments. Then, a three-dimensional model of the tuna-like caudal fin was established, and the change of propulsion performance under different swing amplitudes was numerically simulated. Finally, the simulation results were compared and analyzed. The results show that under large swing amplitudes, as the swing amplitude increases, the average thrust coefficient of the caudal fin increases slowly, and the propulsion efficiency decreases rapidly. The research can provide reference and guidance for the design and control of the machines which equip with tuna-like caudal fin.
