Abstract: The breakup process of liquid film when it breaks away from the rotor of a centrifugal apparatus was studied. The effects of the rotor speed, flowrate and physicochemical properties of liquids, such as viscosity, density and surface tension, on the disperse composition of droplets were evaluated. The dispersion process was mathematically described, and calculated dependences that enable the estimation of the diameter of the resultant droplets were obtained. The origination of droplets of the smallest diameter was found to be favored by the increased rotor speed and decreased volumetric flowrate.
