Abstract

The aim of this study is to investigate the behaviour of liquid metal flow in Capillary Porous System (CPS) under strong external magnetic field. Overlapping simple cubic (SC) periodic array of electrically non-conducting spheres with diameter 6 mm and distance between spheres centres 5.6 mm is 3D printed from PLA electrically non-conducting filament. At room temperature, flow of up to 50 mL/s of In–Ga–Sn in pore space in magnetic field of superconducting magnet up to 5T is investigated. Three orientations of magnetic field in relation to the main flow in SC cell are considered—colinear with main flow and perpendicular to it. The values of Reynolds, Hartmann and Stuart numbers in experiment are up to 1160, 90 and 350, respectively. The results indicate that parallel to the main flow orientation of magnetic field has little influence on the flowrate, while perpendicular orientation strongly reduces flowrate with dependence close to 1/Ha, which agrees well with ANSYS Fluent simulations in a unit SC cell, resembling results for channel flow in magnetic field.

简单三次周期阵列几何中的MHD流

本文研究了强外磁场作用下毛细孔系统中液态金属的流动行为。采用聚乳酸(PLA)导电丝3D打印出直径为6毫米、中心间距为5.6毫米的重叠简单立方(SC)导电球体周期阵列。在室温下，研究了在5T超导磁体磁场下in - ga - sn在孔隙空间中高达50 mL/s的流动。考虑了与SC槽内主流有关的磁场的三个方向——与主流共线和垂直于主流。实验中的Reynolds数、Hartmann数和Stuart数分别高达1160、90和350。结果表明，与磁场主流方向平行对流量影响不大，而垂直方向对流量影响较大，且影响程度接近1/Ha，这与ANSYS Fluent在单位SC胞内的模拟结果吻合较好，与磁场作用下通道流的模拟结果相似。

期刊介绍： The Journal of Fusion Energy features original research contributions and review papers examining and the development and enhancing the knowledge base of thermonuclear fusion as a potential power source. It is designed to serve as a journal of record for the publication of original research results in fundamental and applied physics, applied science and technological development. The journal publishes qualified papers based on peer reviews. This journal also provides a forum for discussing broader policies and strategies that have played, and will continue to play, a crucial role in fusion programs. In keeping with this theme, readers will find articles covering an array of important matters concerning strategy and program direction.
