| 摘要: |
| 为研究航行状态下舰船混合电场的产生机理及变化规律,基于电化学原理及流体动力学相关理论,分析湍流流场、舰船电场等多物理场耦合建模理论基础,结合轴频电场中舰船轴系机械结构等效电路电阻变化规律,最终采用边界元法建立湍流介质条件下潜艇腐蚀混合电场模型,分析不同螺旋桨转速及介质流速下舰船静电场及轴频电场变化规律。结果表明:螺旋桨转速由0 r/s增长至1、2、3、4 r/s时,螺旋桨正下方2B(B为船宽)处舰船混合电场幅值依次增长了66.5%、13%、3.7%、1.19%,且混合电场频率与螺旋桨转速一致。该模型对分析运动状态下舰船电场变化规律提供了理论参考。 |

| Abstract: |
| To study the generation mechanism and variation law of ship electric field under navigation conditions, combining electrochemical principles and fluid dynamics related theories, analyzing the theoretical basis of multi-physics modeling such as turbulent flow field and ship electric field, and combining the equivalent resistance change law of the ship shafting mechanical structure in the axial frequency electric field, finally adopts the boundary element method Establish a submarine corrosion mixed electric field model under turbulent medium conditions, and analyze the changes of the ship′s electrostatic field and axial frequency electric field under different propeller speeds and medium flow rates. The results show that when the propeller speed increases from 0 to 1,2, 3,4, the electrostatic field of the ship at 2B(B is breadth of ship) directly below the propeller increases by 66.5%, 13%,3.7%, and 1.19%, and the frequency of the mixed electric field is consistent with the propeller speed. This model provides a theoretical reference for analyzing the changing law of the mixed electric field of a ship in motion. |
