Abstract: A
magnetohydrodynamic model is developed to predict the convection velocity inside
electromagnetically-levitated molten alloy droplets utilizing a commercial computational
fluid dynamics package. The internal convection velocity of levitated molten Fe50Co50
droplet is simulated versus testing temperature, sample undercooling, coil current and
control voltage in electromagnetic ... read morelevitation experiments in support of future
microgravity materials experiments on board the International Space Station. The range
of internal convection velocity for the levitated molten samples is evaluated and used
to define the accessible Reynolds number to identify the laminar-turbulent transition
behavior for these experiments.
