Conveying of coarse particle in non-Newtonian slurry
Abstract eng: The paper deals with flow behaviour of slurries containing colloidal, clay, dust and also coarse-grained particles. The slurry flow behaviour changes from Newtonian to non-Newtonian in dependence on the solid phase concentration and composition, especially on the contents of colloidal particles. Flow behaviour of fluidic fly and bottom ash slurries, clay and sand slurries was experimentally investigated with respect to the solids composition, volumetric concentration and slurry velocity. The re-circulation pipe loop with smooth stainless steel pipes of the inner diameters D = 17.5, 26.8 and 36 mm was used for measuring the slurry flow parameters. Also the effect of time and intensity of shearing was studied for time dependent fluidic ash slurries.
