| 摘 要： | 在标准Rushton涡轮桨的基础上,从不同形状的搅拌罐底、挡板形式以及桨叶的非对称结构布局三个方面分别探究其对搅拌效果的影响,利用ANSYS CFX软件对不同结构搅拌桨的搅拌功率、流体速度、流动方向以及剪切速率进行对比分析。研究结构表明：流线型蝶形罐底有助于降低功耗,挡板能够消除打漩现象并增强剪切速率,不对称的结构布局能够破坏周期流中的规则区,改善搅拌效果。

| Abstract: | Based on the standard Rushton turbine blade, the effects of different shapes of the mixing tank bottom, the baffle form and the asymmetric structure layout of the blade on the mixing effect were explored. The ANSYS CFX software was used to stir the paddles of different structures. The mixing power, fluid velocity, flow direction, and shear rate were compared for analysis. The research structure shows that the streamlined butterfly can bottom helps to reduce power consumption, the baffle can eliminate the swirling phenomenon and enhance the shear rate, and the asymmetric structure layout can destroy the regular zone in the periodic flow and improve the stirring effect. |

| Keywords: | stirred tank bottom baffle structural layout mixing performance flow field simulation |
