通过CFD模拟和实验功率验证，研究了间歇式转子-定子混合器的功率与流动特性之间的关系。所研究的混合器为Silverson 15M型标准乳化头间歇式混合器。屏幕上的孔的大小和基孔的收缩以小的增量改变。采用磁流变液技术对转子旋转进行建模。在这项研究中，建立了一个将混合器的功率和流量联系起来的模型。由于功率很容易通过实验测量，因此可以使用该模型通过测量扭矩来预测流量数。还开发了第二个模型，该模型允许仅使用混合头的几何形状来预测流动数。这一研究极大地加深了我们对转子-定子混合器中功率、流量和混合器几何形状之间关系的理解。
The relationship between power and flow characteristics of batch rotor-stator mixers has been studied using CFD simulations with experimental power validation. The mixer studied was the Silverson L5M batch mixer with the standard emulsor head. The size of the holes in the screen and the constriction of the base hole were changed in small increments. The MRF technique was used to model rotor rotation. A model is developed in this study which links the power and flow numbers of the mixer. Since power is easy to measure experimentally, one can use this model to predict the flow number by measuring torque. A second model is also developed which allows one to predict the flow number using solely the geometry of the mixing head. This study greatly enhances our understanding of the relationship between power, flow and mixer geometry in rotor-stator mixers.
