ASSESSING THE SIZE DISTRIBUTION OF DROPLETS OBTAINED IN A CENTRIFUGAL MASS-EXCHANGE APPARATUS

Consideration has been given to the basic mechanisms of fragmentation of droplets in the system "liquid–liquid" in fi lm fl ow over the working surface of the rotor of a centrifugal mass-exchange apparatus. The authors have assessed theoretically the sizes of dispersed-phase droplets on separation of the liquid fi lm from the rotor′s working surface and its arrival at a toroidal clearance between the intake tube and the rotor of the apparatus. It has been established that the greatest infl uence on the formation of the particle-size distribution of an emulsion is exerted by shear stresses in the liquid that arise in the toroidal clearance. The infl uence of the rotor speed and the rate of fl ow of the liquid on the size distribution of droplets of the obtained emulsion has been shown. Good agreement between theoretical and experimental data has been confi rmed experimentally
