摘要

作为昂贵或不可用的 X 射线和中子成像技术的一种简单而经济的替代方法，本文介绍了一种改进的光学成像方法，用于测量 Hele-Shaw 液体金属池中的气泡流动，其液态金属层厚度大大超过了之前的报道。这样就可以在没有或有外加磁场的情况下，研究不同几何限制程度的气泡动力学。实验的主要原理、实验装置以及必要的图像/数据处理管道均有描述，初步结果表明，所提出的方法可用于量化不同气体流速和磁场配置对 Hele-Shaw 室中气泡链流动的影响。

Optical imaging of MHD bubble flow in Hele-Shaw liquid metal cells

As a simple and affordable alternative to often prohibitively expensive or unavailable X-ray and neutron imaging, an improved optical imaging method for bubble flow in Hele-Shaw liquid metal cells is presented, enabling measurements with a significantly greater liquid metal layer thickness than previously reported. This enables studying bubble dynamics with varying degrees of geometric confinement, without or with applied magnetic field. The main principles and the experiment setup as well as the necessary image/data processing pipeline are described, and preliminary results show that the proposed methods can be used to quantify the effects of varying gas flow rate and magnetic field configuration on bubble chain flow in a Hele-Shaw cell.

期刊介绍： Experiments in Fluids examines the advancement, extension, and improvement of new techniques of flow measurement. The journal also publishes contributions that employ existing experimental techniques to gain an understanding of the underlying flow physics in the areas of turbulence, aerodynamics, hydrodynamics, convective heat transfer, combustion, turbomachinery, multi-phase flows, and chemical, biological and geological flows. In addition, readers will find papers that report on investigations combining experimental and analytical/numerical approaches.
