Abstract

Design of centrifugal extractors requires exact knowledge of fluid dynamic processes particularly the formation and motion of drops in the rotating liquid-liquid system. The flow of a denser dispersed phase was examined in a transparent centrifugal rotor fitted with perforated cylindrical sheets. The relationships pertaining to the formation of drops on rotating perforated sieve plates are described from the detachment of individual drops via jet break-up right up to atomization. Peculiarities of jet trajectories in the rotating system, mean drop sizes and size spectra are dealt with in detail. The effect of drop deformation, occurring at high centrifugal field intensities, on drag coefficients and drop stability is discussed.
