Název v původním jazyce

Effect of particle size distribution and concentration on flow behavior of dense slurries

Popis výsledku v původním jazyce

The article deals with experimental investigation of the flow behavior and pressure drop of dense complex slurries containing sand of different particle size distribution (with mean diameters ranging from 0.20 to 1.40 mm), stony dust (mean diameters of 0.008 mm and 0.033 mm), or clay conveyed in water. The slurries were tested using experimental pipeline loops with inner diameters of 17.5 and 26.8 mm. The slurry volume concentrations range from 6% to 40% for sand slurries, from 26% to 48% for stony dustslurries, and from 45% to 51% for stony dust-sand slurries. The study revealed the time-independent yield pseudo-plastic behavior of the concentrated fine-grained stony dust slurries and the possibility of reducing their flow resistance by adding coarse-grained material. The flow behavior of the stony dust slurries can be approximated by the Herschel-Bulkley or the Bingham model in the laminar region and by the Wilson model in the turbulent region.
