In the last 5 years, an extensive experimental campaign was carried out in our test loops composed of horizontal, inclined, and vertical pipes. Several fractions of glass beads (from fine to coarse), gravel and basalt pebbles were used to prepare settling slurries of different properties. During the tests, different patterns of slurry flows were observed. The tests included measurements of concentration distribution (vertical profiles and tomograms) of solids in a cross section of the slurry pipe. The paper analyzes measured flow resistance curves and concentration distributions with an aim to recognize flow patterns and dominating particle-dispersion mechanisms in the observed slurry flows. Besides the particle-support mechanisms also friction mechanisms are studied and modeled in order to get a complete picture of the behavior of the settling slurry flow at each specific condition. Models are presented for predicting flow resistance curves and concentration profiles.
