摘要:

设计了用于水平磁场中锂膜流动铺展性及磁流体动力学效应研究的实验装置,介绍了所用磁铁、锂循环回路、动力系统、回路温控系统和测量系统五个组成部分。各部分加工完成,进行现场组装与回路调试,最后加入锂锭熔融后完成实验台搭建工作。利用该实验台研究了锂膜在不锈钢表面的铺展情况、锂膜表面形态与流动雷诺数的关系,以及磁场对液膜表面形态的影响等方面。结果发现液态锂膜在充分锂浸润的不锈钢表面能够完全铺展,水平磁场对锂膜流动有致稳作用,并且可以抑制磁场方向的表面波动。

Abstract:

An experimental station, consisting of the magnet, the lithium flow loop, the dynamical circulation system, the heating system and the measure system, has been designed to study the liquid lithium film flow under a horizontal magnetic field. After the parts of the experimental facility are fabricated well and moved into the laboratory, the experiment station is assembled and tested on-site. At last, the experimental station is completed after the solid lithium is filled in and melted. Then, some experiments are conducted, including the lithium spreading performance on stainless-steel surface, the lithium film flow patterns under varying Reynolds numbers, and the MHD effects on the lithium film flow. The result shows that the liquid lithium film could spread well on the stainless steel which had been wetted by lithium sufficiently, and the horizontal magnetic field could steady the film flow pattern and restrain the surface wave of the film on the magnetic direction.

Key words: Plasma facing materials (PFM), Liquid lithium film flow, Horizontal magnetic field, Magnetohydrodynamics (MHD)
