Abstract
Observing and predicting the dynamics of levitated liquid droplets has been a source of valuable fundamental and practical knowledge due to the absence of the free surface interaction to solid walls. Various types of magnetic fields are used to compensate the integral effects of gravity for the liquid levitation. Metallic samples, melted using the Electro Magnetic levitation technique, are prone to oscillation and instability when AC magnetic field is used. Intense internal fluid flow is observed, apparently being in the turbulent regime for earthbound and even in the microgravity conditions. Alternatively, a high DC magnetic field levitation, using para- and dia-magnetic properties of the materials, can be used for advanced material research without the drawbacks related to the intense recirculating turbulent flow vortices appearing.The time dependent numerical models based on accurate spectral approximation give an insight to oscillation patterns, stability and the sensitivity to boundary conditions for liquid samples in AC and DC fields.Applications to microgravity experiments planned at International Space Station and the full gravity magnetic levitation for the similar samplesare investigated using the numerical model. The numerical predictionsfor a larger size liquid volumelevitation techniques offer insight to new possibilities.
