摘要

摘要:
为抑制水下推进器螺旋桨空化的形成, 提高其水动力性能, 基于泵喷整流机理, 以导管螺旋桨推进器为研究对象, 分别设置前置定子和后置定子, 利用计算流体力学仿真分析和实验的方法, 研究了前、后定子对导管推进器的空化抑制、扭矩平衡及推进效率等方面的影响。研究结果表明, 前置定子对空化抑制效果明显, 相对弯度对提高推进效率的影响显著, 能够平衡部分横滚扭矩; 后置定子对抑制螺旋桨尾流区的空化效果明显, 剖面弦径比和安装位置对提高推进器效率和扭矩平衡具有最优值。因此可以通过在导管螺旋桨上加装合适的前后定子, 降低螺旋桨的噪声等级, 优化螺旋桨的空化性能, 提高水动力性能, 为类泵喷推进器的结构设计提供参考。

Abstract:
To prevent cavitation of underwater propellers and improve hydrodynamic performance, based on pump jet rectification mechanism, front and rear stators were installed for conduit propellers. The effects of front and rear stators on cavitation suppression, torque balance, and propulsion efficiency of conduit propellers were studied by computational fluid dynamics simulation analyses and experiments. The results showed that the front stator has an effect on cavitation suppression, and the relative bending has a significant effect on improving the propulsion efficiency, which can balance part of the roll torque. The rear stator has an effect on restraining cavitation in the wake area of the propellers. The section-chord diameter ratio and installation position has the greatest effect on improving the efficiency and torque balance of the propellers. Therefore, the noise level of the propeller can be reduced, cavitation performance can be optimized, and hydrodynamic performance can be improved by installing proper stators before and after the conduit propeller, which provides an important reference for future structural designs of the pump jet propellers.
