Abstract

Modeling the gravitational field-induced or centrifugal field-induced separation of particles of a dispersion by use of one or more additional force fields that also influence the migration of the particles. A method includes detecting and measuring the modified separation behavior with the help of concentration-measuring sensors. The force acting upon the particles can be calculated from the change in velocity of the particles, and the corresponding particle properties can be calculated if the respective field intensities are known.
