Numerical simulation of liguid alloy flow field during solidification under applied pulsed magnetic fields

A numerical simulation of the flow field during solidification in Al-alloy was corried out by the ANSYS 55 in the present paper. The simulation results were in good agreement with the experimental data. It was found, through the simulation, that not only the melt's movement but also the mechanism of the refinement for the solidified structure and the formation of some defaults during solidification were elementally understood.
