Experimental investigation of coarse-grained particles in pipes

Popis výsledku v původním jazyce

The effect of solid concentration and mixture velocity on the flow behaviour and pressure drops of coarse-grained particle-water mixtures in the turbulent flow was experimentally investigated. Concentration distribution in the pipe cross-section was alsostudied. Graded basalt pebbles as a model of solid particles were studied on an experimental pipe loop with horizontal, vertical, and inclined sections of smooth stainless steel pipes of inner diameter D = 100 mm. The study revealed that the coarse-grained particle-water mixtures in the smooth horizontal and inclined pipes were significantly stratified. The coarse-grained particles conveyed by liquid in pipe moved principally close to the pipe invert, however for higher and moderate flows velocities, particle saltation becomes dominant mode of particle sediment transport. Frictional pressure drops in vertical pipe were found to be less than in horizontal pipe section.
