Abstract

Numerical models are used to investigate behavior of a solid body or liquid droplets suspended in AC and DC magnetic fields of various configurations providing conditions similar to microgravity. The realistic gradient fields, as in superconducting magnets, are used for the modeling experiments with electrically conducting droplets. The oscillations in a high DC magnetic field are different for an electrically conducting droplet. At the high values of magnetic field some oscillation modes are damped quickly, while others are modified with a considerable shift of the oscillating droplet frequencies and the damping constants from the non-magnetic case. On a larger scale, the models are used to investigate the melting process of reactive materials, for example titanium alloys. If the contact is avoided, thermal losses could be limited only by radiation and possible evaporation.
