在本研究中，建立了磁-热-流体动力学-锂（MaTH-Li）回路，对液态金属（LM）组分进行基础研究。在锂离子LM组件实验的第一步，我们根据Hu等人的建议设计了LM限制器。(诊断。Fusion, 2016, 56,046,011)来检查锂流在面积为300×298 mm2的板上的扩散特性。通过在固定的60◦倾斜角度改变锂的流速，用相机捕捉锂流在限位器上的扩散特性。我们的实验结果表明，液态锂几乎可以覆盖整个限位器表面，其覆盖率达到97.32%，是目前报道的最高的。此外，自由表面锂流动可以在一定的流速范围内保持，这证明了目前的LM限制器的稳健性。然而，由于限流器表面的锂在20天后氧化，流动的锂在限流器表面的覆盖率下降到84%，这与EAST装置中FLiLi的结果相似。在一些不受外磁场影响的典型流动条件下，会出现锂溅射现象，其平均锂液滴尺寸为0.175mm，这需要在LM限流器的设计中进一步改进。
In the present study, the Magneto-Thermo-Hydrodynamic-Lithium (MaTH-Li) loop is established to carry out fundamental studies on the liquid metal (LM) components. In the first step of our experiments on lithium LM components, the LM limiter is designed according to suggestions from Hu etal. (Nucl. Fusion, 2016, 56, 046,011) to check the spreading characteristics of lithium flow on a plate with an area of 300×298 mm2. By changing the flow rate of lithium at a fixed tilt angle of 60◦, the spreading characteristics of lithium flow on the limiter are captured by a camera. Our experimental results reveal that the liquid lithium can cover nearly the whole surface of the limiter, with a coverage ratio of 97.32%, which is the highest one reported. Moreover, the free surface lithium flow can keep for a range of flow rates which proves robust to the present LM limiter. However, due to the oxidation of lithium on the surface of the limiter after 20 days, the coverage ratio of flowing lithium on the limiter surface reduces to 84%, which is similar to the results of FLiLi in the EAST device. The lithium splashing with an average lithium droplet size of 0.175mm appears in some typical flow conditions without the influence of an external magnetic field, which needs further improvements in the design of the LM limiter.
