CFD method for evaluation of critical impeller speed required for floating particles suspension
Languages of publication
In the paper, critical impeller speeds were analyzed on the basis of the performed simulations of the concentration distribution of the floating particles suspension in an agitated vessel, equipped with pitched blade turbine. The required range of the standard deviation of the local particles concentration in a suspension was assumed as comparative criterion. The results obtained from numerical computations were compared with the values of the critical impeller speeds determined experimentally.
