提出一种油气管道裂纹漏磁场检测的数学分析方法。先根据麦克斯韦方程组推导出漏磁场数据分析模型。其次,利用三维有限元分析原理在Ansys环境下建立数学仿真模型。再将仿真结果与实际测试数据进行比较,确定该方法的可靠性。最后,通过仿真分析得出了裂纹几何参数(深度和宽度等)对漏磁信号特征的影响规律,并给出它们的关系曲线。该方法为实际利用漏磁场分布检测油气管道裂纹提供了重要的依据。 相似文献

The aim of this article was to theoretically study diffusion and migration of chlo-ride ions during electrochemical chloride removal. The proposed model would enable optimization of its application by predicting the optimal treatment time and current combination. A mathematical model for simulating the transport behavior of chloride ions was developed by consideration of diffusion and migration of chloride ions when a constant DC current density was applied through the marine cast iron artifacts. The corresponding tests were conducted to validate the mathematical model. This model predicted the data of the extraction ratio of the chloride ion that correlated satisfac-torily with the experimental values. An important issue in electrochemical chloride removal was to understand how chloride ions moved, taking account of diffusion and migration of chloride ions and the release of binding chloride ions. The effects of the treatment time, externally applied current density, chloride diffusion coefficient, and rate constant of release of binding chloride ion on chloride removal are studied. The specific quantitative details applied to one-dimensional model were discussed here. This article has proposed a mathematical model for the first time, which was showed to be a useful tool that can reveal the ionic transport mechanism and optimize the application during electrochemical chloride removal. 相似文献
