摘　　要：用Fluent模拟分析了旋转喷吹净化流场气液两相流,考察了旋转速度、进气量、有无阻流板对氩气气泡分布的影响。结果表明:旋转速度较低,进气量较小时,设置阻流板能明显提高氩气气泡的分布,获得较好的精炼效果。旋转速度较高,进气量较大时,无阻流板时气泡分布、净化效率更高。Commercial Fluent was used to simulate and analyze the gas-liquid two-phase flow field of rotary purification.The effects of rotational velocity and argon flow rate on the distribution of argon bubbles with or without spoiler were investigated.The results show that the distribution of argon bubbles can be improved obviously with spoiler when the rotation speed is low and the argon flow rate is small.When the rotation speed is higher and argon flow rate is larger,the bubble distribution and purification efficiency are higher without spoiler.

关 键 词：气液两相流 旋转喷吹 净化效率
