| 摘 要： | 本文采用ＣＯ２吹入并溶解于 ＫＯＨ溶液的模型，模拟研究了液体金属的吹气精 炼工艺中气泡的行为及其对表观传质系数的影响。研究结果表明，气泡行为随喷孔雷 诺数而变化；表观传质系数主要取决于喷孔直径和喷孔雷诺数；增大表观传质系数的 关键在于尽可能减小气泡形成时的尺寸。

| Abstract: | A study is made of the behaviors of bubbles and the effect of it on apparent mass transfer coefficient in the processes of gas purifying molten metals through the process of CO2 blowing and dissolving into KOH solution. The results show that the behaviors of bubbles change along with Reynolds number; apparent mass transfer coefficient mainly depends on the diameter and Reynolds number of orifice; the key of increasing apparent mass transfer coefficient is decreasing bubble size during bubble formation. |
