针对船舶绿色化转型与操纵性能提升的双重需求，提出一种新型制流板电磁扰流舵（EEPCSR），并对其水动力性能开展综合分析。利用分离涡模拟方法，对常规舵、制流板舵、扰流舵（CSR）及EEPCSR开展敞水水动力数值模拟。通过网格收敛性分析研究确定了最佳网格划分策略，并结合模型试验验证了方法可靠性。结果表明，制流板可有效抑制舵叶端部绕流，扰流板显著提升舵升力，二者协同作用实现舵效能强化与效率补偿；通过调控舵角与扰流板张开角，等升力条件下EEPCSR效率相对常规舵最大提升31.2%。该研究将为新型节能舵装置的工程设计与应用提供借鉴和理论支撑。

To address the dual demands of ship green transformation and maneuverability improvement, a novel electromagnetic end-plate collaborative spoiled rudder (EEPCSR) is proposed, and a comprehensive analysis of its hydrodynamic performance is conducted. Using the detached eddy simulation (DES) method, the hydrodynamic numerical simulations under open-water are carried out for the conventional rudder, the end-plate rudder, the collaborative spoiled rudder (CSR), and the EEPCSR. The optimal grid generation strategy is determined through grid convergence analysis, and the reliability of the method is verified by combining with model test results. The results show that the end plate can effectively suppress the rudder tip flow separation, while the spoiler significantly enhances the rudder’s lift; their synergistic effect achieves both enhanced rudder effectiveness and efficiency compensation. By adjusting the rudder angle and spoiler open angle, the efficiency of the EEPCSR is maximally improved by 31.2% under the constant lift condition compared with the conventional rudder. This study will provide reference and theoretical support for the engineering design and application of new-type energy-saving rudder devices.
