Three groups of particles, of different densities but the same diameter, are included. They are such that the first group is denser than the continuous phase, the second group is neutrally buoyant and the third group is less dense. ///////////////////////// ------------------------- north wall y^ | --> in --> out (3 exits) | ----> ------------------------- south wall x ///////////////////////// ENDDIS ************************************************************ Group 1.
