Název v původním jazyce

Solid particle distribution of moderately concentrated suspensions in a pilot plant stirred vessel

Popis výsledku v původním jazyce

Detailed particle distribution of a solid-liquid suspension in the just suspended state was measured by means of a conductivity probe. A total of eight experimental settings were investigated, involving two particle diameters (0.14 and 0.35mm), two average particle concentrations (5 and 10 vol. %) and two impeller off-bottom clearances (H2/d = 1 and 0.5). A pilot plant stirred vessel of one meter in diameter stirred with flat six pitched-blade turbine was used. A particle-filled layer of suspension wasobserved in all these experiments, and was particularly pronounced at the solid concentration of 10 vol. % and impeller off-bottom clearance H2/d = 0.5. The local solid concentration profiles within this layer were investigated. The axial and radial concentration gradients and their standard deviations were determined.The results indicate the presence of a concentration gradient in the radial direction within the particle layer, and of significant concentration fluctuations at the interf
