摘要: Abstract The scope of this work is the numerical calculation three-dimensional, time-dependent velocity and concentration fields in cylindrical bubble columns with two-phase gas-liquid thre-phase gas-liquid-solid flow. Therefore all phases are described by an Eulerian approach. In particular local interfacial area density interphase transfer terms for mass momentum calculated based on a population balance equation proposed approach enables effective way to couple computational fluid dynamics. For three-phase flow heavy particles diameters range 100 μm considered as catalyst heterogeneous chemical reaction. solids phase viscosity pressure granular theory. influence coalescence has been investigated extend model. From obtained.
