本文的目的是概述CFD工具解释臭氧接触系统中发生的不同物理和化学现象的能力。研究了配备细气泡多孔板扩散器的常规臭氧氧化室。数值模拟方法和在每个反应器上获得的各自实验数据准确地描述了气液两相流的流体动力学,并评估了每种情况下臭氧传质的效率。这项工作表明,CFD建模是一个有用的工具,可以描述不同全尺寸臭氧氧化反应器中的流体动力学和传质效率,并提出升级设计以实现更高的性能。包括11个参考文献、表格、图表。
The objective of this paper is to give an overview of the capabilities of the CFD tools to account for the different physical and chemical phenomena occurring in the ozone contacting systems. Conventional ozonation chambers equipped with fine bubble porous plate diffusers are studied. The numerical modeling approach and the respective experimental data obtained on each reactor describes accurately the hydrodynamics of the two-phase gas-liquid flow and to evaluate the efficiency of ozone mass transfer in each case. This work demonstrates that CFD modeling is a useful tool to characterize the hydrodynamics and mass transfer efficiency in different full-scale ozonation reactors and to propose an upgraded design to achieve higher performance. Includes 11 references, tables, figures.
