Abstract

This article studies the optimal design approach for a portable nuclear magnetic resonance (NMR) system for use in non-destructive flow measurement applications. The mechanical and electromagnetic design procedures were carried out using the Ansys Maxwell finite-element analysis (FEA) software tool. The proposed procedure considered homogeneity and strength constraints while ensuring the desired functionality of the intended device for a given application. A modified particle swarm optimization (MPSO) algorithm was proposed as a reference design framework for optimization stages. The optimally designed NMR tool was prototyped, and its functionality was validated via several case studies. To assess the functionality of the prototyped device, Larmor frequency for hydrogen atom was captured and compared with theoretical results. Furthermore, the functionality and accuracy of the prototyped NMR tool is compared to the off-the-shelf NMR tool. Results demonstrated the feasibility and accuracy of the prototyped NMR tool constrained by factors, such as being lightweight and compact.

便携式核磁共振系统的设计挑战

本文研究了用于非破坏性流量测量的便携式核磁共振(NMR)系统的优化设计方法。采用Ansys Maxwell有限元分析(FEA)软件进行机械和电磁设计。拟议的程序考虑了均匀性和强度限制，同时确保给定应用的预期设备的预期功能。提出了一种改进的粒子群优化算法(MPSO)作为优化阶段的参考设计框架。优化设计的核磁共振工具原型，并通过几个案例研究验证了其功能。为了评估原型装置的功能，捕获了氢原子的拉莫尔频率，并与理论结果进行了比较。此外，原型核磁共振工具的功能和准确性与现成的核磁共振工具进行了比较。结果证明了原型核磁共振工具的可行性和准确性，但受到重量轻、结构紧凑等因素的限制。
