Abstract

The research aim is to determine the influence of regime parameters on the hydrodynamic characteristics of a single-stage high shear mixer with the “rotor-stator” arrangement of operating devices and compensation of axial pressure in the end clearance between the rotor and the housing. The dependences of volume flowrate, apparatus input and output pressure drop and engine energy consumption from rotor rotation frequency at different degrees of overlapping of passage section on the outlet pipeline, as well as the dependences of apparatus pressure drop, engine energy consumption and hydraulic efficiency from volume flowrate at constant rotation frequency of the drive shaft have been suggested according to the experimental results. The possibility of applying the principles of blade machines theory to the analysis of operation of the high shear mixer with considered design has been confirmed. The absence of a qualitative effect of penetrating side perforation of the rotor on hydraulic characteristics of the high shear mixer in cases with small areas has been proven. It has been determined that for the researched design of the high shear mixer the hydrodynamic component of power inputs does not exceed 4 %, and consequently does not significantly affect the total energy consumption of the apparatus, although the amount of energy is sufficient to create a pressure drop that is necessary to ensure the operation of the apparatus in the in-line mode without using additional equipment and integrated devices.
