摘要
1 前言中低粘度的异粘物系,一般以小桨叶进行搅拌混合。已有文献分析了这类混合特征,并指出实现混合必须超过一定的R_e数;还有文献讨论了密度差的影响。本文就小于1Pa·s范围内的异粘液体,用不同类型小桨叶搅拌,进行了混合过程观察。
In a stirred tank the mixing of liquids of different viscosities was investigated by using three types of turbine impeller. The viscosity of the more viscous liquid is 1 pas. From flow pattern observations, the suction-discharge phenomenon and its mixing effect was especially studied. The effect of impeller configuration was discribed by the correlation of power consumption vs. mixing time. Furthermore, the critical rotating speed for the suction-discharge was also roughly analyzed on the basis of laminar m...
