本文对均匀磁场作用下金属熔体中的自然对流进行了实验研究。工作流体是熔融的镓，其被包含在具有保持在不同温度下的两个相对的垂直壁的矩形盒中。施加的磁场平行于温度梯度。温度场和速度场都是在有和没有外加磁场的情况下测量的。在系统中的对流的数值模拟也进行了使用的数值模型在以前的研究中开发的。良好的协议之间存在的测量和计算结果的条件下研究。结果表明，外加磁场抑制了自然对流，磁阻尼效应随外加磁场强度的增加而增强。
This paper presents an experimental investigation on natural convection in a molten metal subject to a uniform magnetic field. The working fluid is molten gallium, which is contained in a rectangular box with the two opposite vertical walls held at different temperatures. The imposed magnetic fields are parallel to the temperature gradient. Both the temperature and velocity fields are measured with and without an imposed magnetic field. Numerical simulations of convective flows in the system are also performed using the numerical model developed in a previous study. Good agreement exists between the measured and computed results for the conditions studied. Results show that natural convection is suppressed with an imposed magnetic field and the magnetic damping effect increases with an increase in the applied field strength.
