| 摘 要： | 针对离子迁移漂移管的设计优化,本文建立了一种包括气流和电场的多物理场模拟研究方法。对漂移管进行气路仿真,定性研究其中气流的运动,考察是否存在涡流等影响漂移管性能的因素。利用漂移管中气流速率分布,研究常压下离子在电场与气流共同作用下的迁移过程。根据模拟得到的离子迁移谱图,对漂移管的性能进行了分析。结果表明,该方法能够有效地模拟离子在漂移管中的迁移运动,对漂移管的优化设计有着重要的意义。

| Abstract: | In order to design and optimize drift tube in ion mobility spectrometer,a multi-physics simulation method for drift tube has been established in this paper.By simulating gas movement, factors that affect the performance of the drift tube such as turbulence were studied.Then making uses of the Flow velocity vector,we researched the migration process of ions under the action of both Electric field and Airflow.According to the ion mobility Spectrum obtained,the performance of the drift tube was analyzed.The re... |
