Mathematical models are applied to simulatemultiphase, turbulent fluid flow in a RH degassing vessel usingFLUENT, including the motion of molten steel, injected argon gas,inclusion particles, and the top free surface. Predicted inclusionremoval rates are validated with measurements based on samplescollected from operating degassers. The results quantify theimportant role of argon gas bubbles on the inclusion removal mechanism.
