摘要

采用Fluent软件分析了不同旋转喷吹参数对铝熔体净化过程流场的影响。结果表明

600r/min偏置搅拌时

熔体内部气泡分布情况最好。熔体流速和湍流强度随转速的增加而增加

随进气量的增加而降低

偏置搅拌能够进一步提高湍流强度

气泡更细小

精炼效率更高。

Abstract

With the help of Fluent Software

effects of variable rotational speeds

argon gas flux and position of impeller on flow field in aluminum melt spinning purification were analyzed.The results indicate that the distribution of the bubbles enhibits desirable with the rotating speed of 600r/min in a centric stirring.With the increase of rotational speed and the decrease of gas flux

flow velocity and turbulent intensity in melt are increased.In a centric stirring

the turbulent intensity is further enhanced

so the bubble size becomes smaller

and refinery efficiency is further improved.
