Přechod z laminárního do turbulentního proudění pro zahuštěné nenewtonovské suspenze
Vlasák, Pavel ; Chára, Zdeněk
The paper deals with flow behaviour of fine-grained highly concentrated non-Newtonian slurries and their laminar/turbulent transition. The non-Newtonian slurry behaviour changes significantly if the laminar flow changes to the turbulent one. Results of experimental investigation of water mixtures of kaolin or fluidic ash in horizontal straight pipes are presented. A pipe loop with hydraulically smooth stainless steel pipes of inner diameter D of 17.5, 26.8 and 36 mm was used to study the slurry flow parameters.
Vliv zrnitostního rozdělení na tokové chování koncentrovaných hydrosměsí obsahujících fluidní popely
Vlasák, Pavel ; Chára, Zdeněk ; Konfršt, Jiří
Most knowledge on the flow behaviour of highly concentrated slurries has been concerned with the slurries containing either fine-grained particles creating homogeneous, often non-Newtonian slurry or coarse-grained particles creating heterogeneous slurry with settling tendencies. The paper deals with the effect of slurry composition and volumetric concentration on flow behaviour of slurries containing colloidal, clay, dust and also coarse-grained particles
