摘要
The fluid flow, heat transfer and the motion of particles (bubbles and solid inclusions)in the molten steel of steel refining ladles, continuous casting tundish, continuous casting mold and strand, and steel ingot casting process are investigated. The k-ε two-equation model is used to simulate the turbulence. Multiphase fluid flow is numerically simulated by the Lagrangian-Eulerian approach, Eularian-Eulerian approach and Volume Of Fluid (VOF) method. The simulation can predict inclusion trajectories, inclusion removal fraction, free surface wave etc., which can be used to optimize the metallurgical operations.
