| Abstract Scope |
Electromagnetic levitation (EML) utilizes a magnetic field to levitate metallic samples and enables fundamental studies of solidification and thermophysical properties. Many solidification studies and thermophysical property measurements require the flow to be quantified; however, the opaque metallic EML samples do not allow direct observation. Instead, computational fluid dynamics (CFD) is used to model electromagnetic stirring and flow behavior. Experiments using an alloy with a miscibility gap have allowed rare opportunity for direct visualization of the flow through contrast between the two liquid phases in the sample. Previous CFD validation cases were performed in ground-based experiments. However, performing EML in microgravity is preferable to introduce lower forces on the sample and result in less stirring. This investigation reliably reproduced a two-phase liquid and used the flow to validate a fluid model from an EML microgravity experiment on a parabolic flight. |
