O článku:
Narrow particle size distribution basalt pebbles of mean particle size 11.5 mm conveyed by water in the pipe
sections of different inclination were investigated on an experimental pipe loop, consisting of smooth stainless steel pipes
of inner diameter D = 100 mm. Mixture flow-behaviour and particles motion along the pipe invert were studied in a pipe
viewing section, the concentration distribution in pipe cross-section was studied with the application of a gamma-ray
densitometer. The study refers to the effect of mixture velocity, overall concentration, and angle of pipe inclination on
chord-averaged concentration profiles and local concentration maps, and flow behaviour of the coarse particle-water
mixtures. The study revealed that the coarse particle-water mixtures in the inclined pipe sections were significantly stratified,
the solid particles moved principally close to the pipe invert, and for higher and moderate flow velocities particle
saltation becomes the dominant mode of particle conveying.
