Numerical Simulation on Semi-Solid Metal Slurry Preparation by A-EMS
A computational model coupling electromagnetic stirring with a macroscopic heat and fluid flow in semisolid A357 alloy slurry preparation by A-EMS was developed. Effects of electromagnetic field on flow field and temperature field were presented successfully. It is shown that more intensive magnetic field, velocity field and thereby temperature field were uniformly distributed in the stirred melt even at commercial frequency, and thus more uniformly fine microstructures were obtained in comparison with normal EMS.
