Lévitation électromagnétique de gouttes – présentation du projet MAGLEV – premiers résultats

Résumé

A good knowledge of the thermo physical properties of liquid metal alloys is of major importance for processing. For this purpose, an electromagnetic levitator may be used. This has been performed in the past by an ESA project called TEMPUS-Containerless Processing in Space. Results were obtained. Nevertheless, stirring motions in the molten drop generate instability problems, and lead to a deteriorated accuracy of the measure. The stirring motions will be studied in the framework of a future ESA project called “MAGLEV". The national french agency CNES is supporting the french part. Our participation is twofold. First, we look at the effect of the modulation of inducting currents on the oscillations of the free surface. The experimental set-up is presented as well as its original device devoted to the driving of the experiment and the diagnostic on a test experiment. Second, a numerical simulation of the device is done. Perspectives of modelling are developed.
