本文通过数值模拟和实验研究了低频调制行波磁场对导电介质中电涡流产生过程的影响。用超声多普勒测速仪对低熔点GaZnSn合金进行了测量。对于数值模拟，使用Comsol Multiphysics软件。考虑了平均雷诺数和脉动雷诺数对电磁冲击强度和低频调制两种模式的依赖关系。确定了反向调制对搅拌过程的积极影响。特别是在液体介质的主要体积中形成小尺度的涡旋结构。
In the present work the influence of low frequency modulation of a travelling magnetic field (TMF) on a process of generation of electro-vortex flows in electrically conducting media are numerically and experimentally investigated. The measurements are carried out on a low melting temperature GaZnSn alloy by means of Ultrasonic Doppler Velocimetry. For numerical simulation, Comsol Multiphysics software was used. The dependencies of average and pulsating Reynolds numbers on the magnitude of electromagnetic impact and two modes of low frequency modulation are considered. A positive influence of reversed TMF modulations on the stirring process is determined. In particular the formation of a small-scale vortex structure in the main volume of liquid media.
