Abstract
High intensities of centrifugal field are of great help in the speeding up of mixing and separation processes. This is of particular importance in the case of liquid systems with small density differences or when short contact times are necessary. The calculation of centrifugal extractors is based mainly on the interfacial area and hence on the mean drop size as well as on the contact times which are closely related to settling velocities in the centrifugal field. In most cases a spherical shape of drops was assumed up to now for the design of many types of extractors. However, this does not apply to high field intensities in centrifuges and leads to considerable errors in calculation. The formation and motion of drops were investigated in a model centrifuge.
