Abstract

The characteristic flow patterns of the three-phase gas-floating particles-liquid system produced in a baffled agitated vessel with two high-speed impellers on the common shaft were experimentally determined. The minimum impeller speeds adequate to obtain loading, complete dispersion and just drawdown (of floating particles) flow patterns for such multiphase system were identified. The results confirmed that there is influence of gas flow rate Vg and particles concentration X on the value of minimum impeller speeds for each flow model (nJD, nL, nCD, nJDG) and gas hold-up ( in analyzed systems.
