Abstract

Conductive liquid metals and their magnetohydrodynamic (MHD) systems are crucial in nuclear energy. Flat linear induction pumps (FLIPs) enhance safety and reliability working as drive components, and the magnetic-fluid coupling behavior within them deserves further study. This study develops a 1D analytical model for rapid performance estimation, incorporating end effects and half-filled slots. In finite element analysis (FEA), 2D/3D decoupled models and 3D fully-coupled MHD models are presented. Experimental results from a small-scale FLIP prototype are compared with the models. Results show that flow structure minimally affects the magnetic field, while electromagnetic forces significantly influence the liquid behavior. At low flow rates, reverse flow occurs locally. These findings advance understanding of FLIP’s coupled physics and energy conversion, aiding optimization for engineering applications.

平板线性感应泵的电磁、流体和能量特性建模与分析

导电性液态金属及其磁流体动力学（MHD）系统在核能中是至关重要的。平板线性感应泵作为驱动元件，提高了工作的安全性和可靠性，其内部的磁流体耦合特性值得进一步研究。本研究开发了一个用于快速性能评估的一维分析模型，其中包括末端效应和半填充槽。在有限元分析中，提出了二维/三维解耦模型和三维全耦合MHD模型。实验结果与模型进行了比较。结果表明，流体结构对磁场的影响较小，而电磁力对液体行为的影响较大。在低流速下，局部发生逆流。这些发现促进了对FLIP耦合物理和能量转换的理解，有助于优化工程应用。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
