Conveying of Solid Particlers in Newtonian and Non-Newtonian Carriers
Original language description
The paper deals with the effect of fine-grained and coarse-grained slurries composition and concentration on their flow behaviour. The fluidic fly and bottom ash slurries and sand slurries were experimentally investigated. Water and kaolin slurries wereused as the carrier liquid for the sand slurries to compare the effect of Newtonian and non-Newtonian carriers. The study revealed a time-dependent yield pseudo-plastic behaviour of the fluidic fly and fly/bottom ash slurries and the possibility of substantial reduction of the flow resistance by mechanical treatment or by the adaptation of particle size distribution. The highly concentrated sand?kaolin slurries show non-Newtonian behaviour. When the carrier kaolin slurry is peptized, the hydraulic gradient in the laminar region becomes markedly lower, and the favourable effect vanishes in the transitional and turbulent regions. The addition of small amounts of kaolin favourably affects the flow behaviour of the sand slurry.
