摘　　要：基于气-液双流体模型和湍流的修正k-ε模型,对底吹氩钢包精炼过程中熔池内流体流动提出了一个新的三维数学模型,应用该模型于120 t VOD的真空底吹氩精炼过程,对单孔及多孔底吹氩条件下钢包内流体的流动作了模拟和估计。Based on the two-fluid （Eulerian-Eulerian） model for a gas-liquid two phase flow and the modified k-ε model for turbulent flow, a new three dimensional mathematical model for the fluid flow in a ladle furnace during argon bottom blowing refining process was proposed and developed. The model was applied to the argon bottom blowing processes in a 120 t VOD furnace, and the fluid flow in the ladle was simulated and estimated under the conditions of bottom blowing processes through single hole and multiple holes.
