Název v původním jazyce

Experimental assessment and CFD simulations of local solid concentrations profiles in a pilot scale stirred tank

Popis výsledku v původním jazyce

An experimental assessment of solid particle distribution in a stirred vessel was performed by conductivity measurements, and for the same solid-liquid system, the capabilities of the Computational Fluid Dynamics (CFD) simulation were investigated.A detailed particle distribution measurement of a solid-liquid suspension at the just-suspended state was carried out in a pilot-plant stirred vessel of one meter in diameter. This baffled stirred tank was agitated with a Pitched Blade Turbine, which generatesan axial-flow pattern in the tank. The water suspension of glass beads of diameter 0.35 mm was studied. Average particle concentration was 5 vol. %. In this mode of experimental arrangement, a particle-filled layer of suspension was observed. Axial andradial particle concentration gradients and their standard deviations were determined.CFD simulations were performed using a two-phase model implemented in the commercial code Fluent 6.2. The Eulerian-Eulerian multiphase model was adopted
