摘要/Abstract

摘要： 为了研究实际海水环境下螺旋桨转速及海水流速对舰船腐蚀静电场的影响，提出了一种层流介质条件下腐蚀静电场的求解方法.结合流体力学及电化学相关理论，建立层流状态下的曲面螺旋桨旋转模型，利用动量积分法和电化学方法分别求解层流介质下曲面桨叶表面的边界层厚度和极限腐蚀电流密度，基于该电流密度建立电偶极子模型对腐蚀静电场进行求解，并通过实验验证结论的正确性.结果表明：层流状态下，静电场的幅值大小随着螺旋桨转速及介质流速的增加而增加，在流速及转速较小时，理论数据与实验数据拟合程度较好.

Abstract: In order to research the effect of propeller rotating speed and flowing velocity on the corrosion static electric field under sea water, a method for the corrosion static electric field under laminar medium is proposed. Combining the theory of hydrodynamics and electrochemistry, the rotational model of curved propeller in laminar flow is established, the momentum integral method and electrochemical method are used to calculate boundary layer thickness and ultimate corrosion current density of curved blade surface in laminar medium respectively. An electric dipole model is established to solve the corrosion static electric field based on the current density, and the correctness of the conclusion is verified by experiments. The results show that the amplitude of electrostatic field increases with the increase of propeller speed and medium velocity. The theoretical data are in good agreement with the experimental data when the velocity and rotational speed are small.

Key words: corrosion static electric field, static electric dipole, laminar medium, momentum integral method, curved propeller, current density
