The breakup behavior of flocs on the centerline of the entry flow of an orifice is investigated. Flocs composed of spherical and monodispersed styrene divinylbenzene copolymer particles of 90μm diameter are injected into the orifice contraction flow of a 24.0 wt% glycerol solution. It is found that flocs are broken before the orifice to a great extent, as well as near the orifice, but not after the orifice. It is also found that the number of particles in the largest floc that can exist in the flow without breaking is proportional to (dVz/dZ) -0.2.
