Abstract

An experimental and numerical study is performed on the fluctuations of a liquid metal flow under the action of electromagnetic forces in a closed volume. The flow is unsteady in the range of considered dimensionless parameters. The region of a solenoid exhibits the most pronounced velocity fluctuations. The amplitude and range of the fluctuations grow along with the Hartmann number.

交变磁场下封闭体内液态金属流动的非定常波动

对密闭体积内电磁力作用下液态金属流动的波动进行了实验和数值研究。在考虑的无量纲参数范围内，流动是不稳定的。螺线管的区域表现出最明显的速度波动。波动的幅度和范围随着哈特曼数的增大而增大。
