Numerical Simulation of Fluid Flow inside a Molten Liquid Metal Droplet located in an Electromagnetic Induction generated by two Different Inducting Currents
Electromagnetic levitation of electrically conductive droplets by alternating magnetic fields is Sa technique used to measure the physical properties of liquid metallic alloys such as surface tension,viscosity,heat capacity.Experiments can be conducted in microgravity,to reduce electromagnetic stirring and shaping of the droplet.The inductor of the EML is composed of a single inductor which two types of voltage are imposed.This type of electrical installation generates a field to center the metallic droplet and another field to heat and excite it.We use a commercial code join to a homemade code to compute flows generated by inducting voltages recorded in the sounding rocket TEXUS-EML-2(Feb2008).In this flight,two samples(Cu75Co25 at%and Al68,5Ni31,5 at%)of 8 mm diameter have been processed.
