摘要

摘要: 水翼是波浪滑翔器波浪动力转换的关键部件, 直接决定了波浪滑翔器的航行性能。文中研究了波浪滑翔器柔性水翼的推进性能, 根据波浪滑翔器工作时水翼的运动特点, 基于COMSOL Multiphysics软件仿真出柔性水翼主动升沉运动下被动变形的过程, 重点研究波浪参数、俯仰运动参数和斯特哈劳尔数对推进性能的影响。仿真结果表明, 在一定范围内, 水翼推进性能随波高、斯特哈劳尔数的增大而增大, 随波周期的增大而减小; 当波周期较大时, 波高和波周期的变化对水翼推进性能的影响较小; 当俯仰周期与波周期相等时, 俯仰运动对水翼推进性能有积极作用。文中结果可为波浪滑翔器被动柔性水翼后续研究提供参考。

Abstract: The hydrofoil is a key component that determines the capability of wave power conversions and the navigation performance of wave gliders. The propulsion performance of a flexible hydrofoil is investigated in this study. The passive deformation process of a flexible hydrofoil under active heave motion is simulated using the COMSOL Multiphysics software according to the motion characteristics of a hydrofoil when the wave glider is working. The effects of wave and pitching motion parameters and the Strouhal number on the propulsion performance of the hydrofoil are investigated. The simulation results show that the propulsion performance of the hydrofoil increases with wave height and Strouhal number and decreases with wave period within a certain range. When the wave period is high, the change in wave height and wave period has little effect on the propulsion performance of the hydrofoil. In contrast, when the pitch and wave periods are equal, the pitching motion has a positive effect on the performance.
