Narrow-graded sand-water slurry was investigated on an experimental pipe loop with inclinable pipe sections of inner diameter 100 mm in the Institute of Hydrodynamics in Prague. The investigation was focused on the effect of the pipe inclination, slurry concentration and velocity on the local concentration distribution and deposition limit. The settling slurries tend to stratify in horizontal and inclined pipe sections, typically exhibiting partial or fully stratified flow. Visualization and local concentration measurements revealed the stratified flow pattern of the settling slurry in inclined pipe sections. The solids distribution varied considerably with the pipe inclination, the degree of stratification was sensitive to pipe inclination and depended on slurry concentration and flow velocity. The observed concentration profiles showed different degrees of stratification for the positive and negative slope of the pipe. The ascending flow was less stratified than the corresponding descending flow. Pracoviště Ústav pro hydrodynamiku Kontakt Soňa Hnilicová, hnilicova@ih.cas.cz, Tel.: 233 109 003 Rok sběru 2020
