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.
Thinning of kaolin slurry
Vlasák, Pavel ; Chára, Zdeněk ; Konfršt, Jiří
After mixing kaolin with water attractive and repulsive forces between kaolin particles initiate process of coagulation and peptisation, respectively. The coagulation process in the kaolin slurry gives rise to voluminous aggregates of kaolin particles, where a great deal of water is fixed.
