摘要：
Method: that can be used to predict agitation power of in-line rotor-stator mixers are considered in this paper. Results of experimental investigations of power draw are presented and interpreted by using proposed phenomenological models and CFD predictions for the Silverson rotor stator 150/250 MS device and its modifications. Results of theoretical analysis lead to extended version of previously used correlation for the agitation power. Based on new correlation and the multifractal model of turbulence the problems of energetic efficiency and scale-up of drop breakage in the rotor stator devices are presented and discussed.
