摘　　要：针对飞机加油时输油管道沉积静电过大而诱发燃爆的问题,该文在对流-扩散方程、静电泊松方程和纳维-斯托克斯方程的基础上,考虑流场-浓度场-电场耦合,建立了飞机注油时管道产生沉积静电的仿真模型,深入揭示了管道油料内电荷的产生、转移和分布规律,同时发现油料流速、带电粒子浓度、材料吸附速率等参数与管壁累积电势呈现正相关性,对输油管道沉积静电预测与防护提供了理论指导。In view of the problem that excessive static electricity deposition during aircraft pipeline refueling may cause combustion and explosion,based on the convection-diffusion equation,electrostatic Poisson equation and Navier-Stokes equation,considering the coupling of flow-concentration field-electric field,this paper establishes a simulation model of static electricity deposition in the pipeline during aircraft refueling,which deeply reveals the generation,transfer and distribution of electric charge in the pipeline oil,and finds the oil flow rate,charged particle concentration,the material adsorption rate and other parameters are positively correlated with the cumulative electric potential of the pipe wall.These conclusions provide theoretical guidance for the prediction and protection of the electrostatic deposition in oil pipelines.
