Research of Multiphase Systems at ICPF AS CR Prague
Zedníková, Mária ; Růžička, Marek ; Drahoš, Jiří
The aim of this contribution is to present to the Czech waste water treatment community the multiphase flow research at the ICPF ASCR. The goal of the research is to understand the basic physical mechanisms of flow systems with two or more phases. The interest covers a broad range of the multiphase flow systems; for instance: production and hydrodynamics of bubbly mixtures, flow regimes and their identification, effect of control parameters on the flow regimes, mass transfer in gas-liquid systems, bubble formation, coalescence and break-up, hydrodynamic interactions of bubbles, interaction of bubbles with solid particles, sedimentation of polydisperse mixtures etc.

Šimčík, Miroslav ; Růžička, Marek ; Havlica, Jaromír ; Drahoš, Jiří ; Teixeira, J.
This contribution is aimed at CFD simulation of hydrodynamics of gas-liquid external loop rectangular airlift reactor using Euler-Euler model. Commercial code Fluent 6.3 is used to solve model equations. The goal of the work was to compare simulation results with experimental data available in literature. Simulated horizontal profiles of liquid and bubble velocity and gas holdup were compared with data from literature.
