Abstract
Eulerian three-dimensional transient simulations have been conducted to study the hydrodynamics of threephase flow inside a slurry bubble column with intermediate and high concentration of solid particles. The present work evaluated the influence of interactions among phases, in the time-averaged numerical results. Predictions were compared with experimental data available in the literature. Analysis of drag models for the liquid-solid and gas-solid interactions plays an important role in the dynamic behavior of a gas-solid-liquid slurry bubble column. The CFD models simulated was capable to predict gas holdup and (gas velocity) x (gas holdup) profiles similarly to that found experimentally.
