Abstract: Particle horizontal transport and vertical entrainment of widely different materials (silica sand, alumina, ceramsite, dry sludge, and wood shreds) are explored by experimental measurements. Experiments have been performed with two very narrow fractions of solids (0.315–0.50 mm and 1.4–1.6 mm) on a laboratory setup. Simple empirical correlations are proposed in terms of the Reynolds and Archimedes criteria for the commencement of the horizontal conveying as well as the vertical entrainment of particles in pipelines.
