Abstract:Since flow blockages are the ultimate form of increased flow resistance, the research emphasis is focused on the mechanisms that lead to blockage. Different blockage mechanisms are observed in different regimes defined by the ratio of particle diameter to tube diameter. For example, for 0.33 D < dp < 0.46D, a shear-induced arching mechanism has been observed, similar to the arching phenomenon common to granular flows. Orthokinetic flocculation occurs when shear-induced particle collisions result in particles attaching by surface forces to form large groups of physically connected particles (flocs). It is also suggested as a mechanism for blockage that occurs when d p < 0.1D.
