Mathematical models are applied to simulate multiphase, turbulent fluid flow in a RH degassing vessel using FLUENT, including the motion of molten steel, injected argon gas, inclusion particles, and the top free surface. Predicted inclusion removal rates are validated with measurements based on samples collected from operating degassers. The results quantify the important role of argon gas bubbles on the inclusion removal mechanism. 1.
