We investigate argon bubble flow in liquid gallium within a container large enough to avoid wall effects. Flow with and without applied horizontal magnetic field is studied. We demonstrate the successful capture and quantification of the effects of applied magnetic field using dynamic neutron radiography and the previously developed and validated robust image processing pipeline, supported by the in silico reproduction of our experiment. Significant reduction of the amplitude of bubble tilt angle variations due to applied horizontal magnetic field is successfully resolved through a 30 mm thick liquid metal layer. Our results clearly show the potential of expanding the range of gas/liquid metal systems that can be studied using downscaled though representative experimental setups.

磁场作用下液态金属厚层中气泡流动的相界动力学

我们调查了一个足够大的容器中的液态镓中氩气泡的流动，以避免壁效应。研究了有无水平磁场作用下的流动。我们演示了使用动态中子射线照相术以及先前开发和验证的鲁棒图像处理管道成功捕获和量化了施加的磁场的影响，并得到了我们实验的计算机模拟的支持。通过施加30毫米厚的液态金属层，成功解决了由于施加水平磁场而引起的气泡倾斜角变化幅度的显着降低。我们的结果清楚地显示了扩大气体/液态金属系统范围的潜力，可以通过具有代表性的实验设置通过缩小比例来研究。
