ABSTRACT

The effect of slurry velocity and concentration on the coarse-grained particle-water mixtures flow behavior and pressure drops was studied in horizontal and inclined pipes of inner diameter 100 mm. The study revealed that the coarse-grained particle-water mixtures were significantly stratified, the particles moved principally in a layer close to the pipe invert, for higher flow velocities particle saltation becomes dominant mode of conveying. Frictional pressure drops in vertical pipe were less than in horizontal pipe, the frictional pressure drops in ascending pipe increases with inclination angle up to about 30 degrees.
