INFLUENCE OF THE SEQUENCE OF ROTOR APPARATUS CYLINDERS DISPOSITION ON CERTAIN LAWS GOVERNING THE APPARATUS OPERATION

Theoretical and experimental investigations were carried out on determination of the effect exerted by the geometrical parameters of the operational elements of a multicylinder rotor apparatus, regime parameters of processing and fl ow rate of the processed medium on the disperse composition of the droplets of emulsions formed in the radial clearance between the cylinders of the rotor and stator. It has been established that the power dissipation in the radial clearance of the apparatus depends greatly both on the order of cylinders disposition in the operational elements of the apparatus and on the fl ow rate of processed medium. The greatest effi ciency of the process of emulsifi cation in the rotor apparatus is attained under conditions where the circumferential velocity profi le has a large curvature near the rotor surface. It has been established that obtaining such kind of profi le is enhanced by an increase in the rate of fl ow of the processed medium through the apparatus in the case if the inner cylinder in the "rotor–stator" pair is the cylinder of the stator, and conversely by a decrease in the rate of fl ow if the inner cylinder is the cylinder of the rotor
