| Abstract Scope |
Oval-shaped ladles are increasingly adopted in secondary steel refining, yet their gas-stirred flow behavior remains underexplored. This study presents a CFD-based investigation of bottom plug gas stirring in an oval-shaped ladle, focusing on the effects of varying gas injection rates and plug activation patterns. A multiphase model combining the Volume of Fluid (VOF) method and the Discrete Phase Model (DPM) is used to simulate transient gas–liquid interactions. Mixing efficiency is evaluated through velocity fluctuations and tracer dispersion analysis. Results show that 34 SCFM and 50 SCFM gas injection rates yield similar mixing times, with 34 SCFM achieving a quasi-steady state more efficiently. Minimal differences in average velocity were observed between single and dual plug activation due to flow redistribution. The optimal configuration was found to be 34 SCFM with both plugs activated, offering efficient mixing with lower gas usage. |
