摘要:
采用FLUENT软件对搅拌器内部流动情况进行了二维数值模拟，研究了不同桨叶直径、桨叶转速和桨叶数对搅拌器内部流场的影响.结果显示：在同一工况下，桨叶直径为600 mm的搅拌效果比桨叶直径为400 mm和500 mm的搅拌效果好；桨叶转速为6rad/s的搅拌效果比桨叶转速为2rad/s和4rad/s转速效果好；八叶桨式搅拌器的搅拌效果较四叶桨式搅拌器和六叶桨式搅拌器稍好.模拟证实搅拌器桨叶直径、桨叶转速和桨叶数的增加有利于搅拌的混合均匀，但桨叶直径和桨叶数的增加使得搅拌器桨叶加工复杂，生产成本提高；桨叶转速也受制于搅拌器和搅拌轴的结构尺寸，不能无限增大.所以需要综合考虑各种因素的影响，才能选出最合适最经济的桨叶直径、转速和桨叶数.
Abstract:
The FLUENT software was used to study the influence of different blade diameter,blade speed on the internal flow inside agitator.The results show that the blade mixing effect under the diameter of 600 mm is better than that under 400 mm and 500 mm;the blade mixing effect under the speed of 6 rad/s is better than that under 2 rad/s and 4 rad/s;the blade mixing effect in eight vane agitator is better compared with the four vane agitator and the six vane agitator in the same condition.It concludes that the increase of the blade diameter,the blade speed and the number of blades benefits mixing uniformly; the increase of the blade diameter and the number of blades makes the manufacture of agitator blade complex and increases its cost;the blade speed is limited by the agitator structure size.So it’s necessary to consider all conditions to select suitable blade diameter,speed and the number of blades.
