摘要

确定了圆柱搅拌槽内产生的功率消耗和流型。锚定叶轮用于保证高粘性流体的搅拌。介绍了叶轮设计的新改进，以提高搅拌速率。首先，将常规锚杆的下角替换为倾斜段，得到情形1。然后增加叶片的数量以达到封闭的圆形形状(案例2)。进一步增加叶片的数量以达到垂直方向的完美圆形叶片(案例3)。最后，再增加一个圆形水平叶片，得到Case No. 4。从得到的结果来看，情况4大大改善了容器内流体颗粒的循环，并产生了最宽的均匀搅拌区域。

Newly suggested shapes of impellers for stirring highly viscous fluids in vessels

The power consumption and flow patterns generated in a cylindrical stirred tank are determined. The anchor impeller is used to ensure the agitation of highly viscous fluids. Newly modifications in the impeller design are introduced to improve the stirring rates. Firstly, the lower corner of the conventional anchor is replaced by an inclined segment to obtain Case No. 1. The number of segments was then increased to reach a closed circular shape (Case No. 2). Further increase in the number of segments was introduced to reach a perfect circular blade (Case 3) in the vertical direction. Finally, another circular horizontal blade was added to obtain Case No. 4. From the obtained results, Case No. 4 provided a great improvement in the circulation of fluid particles inside the vessel and generated the widest well-stirred region.
