| 摘 要： | 用Ansys静磁模块数值模拟了在外加强磁场环境下铁素体矩形通道管中心磁感应强度分布。与文献结果、解析解及实验数据的对比表明，模拟结果与它们基本一致。进一步的数值模拟还表明，铁素体矩形管对其内部的整体磁场分布影响较大，不同区域内产生不同程度的磁力线扭曲及非均匀的磁感应强度分布效应。该分布可能对管道内磁流体动力学效应产生较大影响。

| Abstract: | The magnetic induction intensity distribution at the center of a ferrite rectangular duct under the external strong magnetic field environment is simulated with Ansys magnetostatic module. Compared with the literature results, analytical solutions and experimental data, simulation results are basically consistent with them. Further numerical simulations also show that the ferrite rectangular duct has a great influence on the overall magnetic field distribution inside it, and it induced magnetic field line distortion and non-uniform magnetic induction intensity distribution are different in different regions. This distribution may have a greater impact on the magnetohydrodynamic effects in the duct. |
