| 摘 要： | 综述了近五年冷态气液固三相搅拌反应器的研究成果，阐明近期研究热点已转为热态多相流搅拌反应器的流体力学行为。概述了热态气液两相体系中通气功率、混合时间、局部及总体气含率的研究结果。指出今后研究重点应为热态的固液悬浮、气液传质过程及其机理，同时说明用计算流体力学（CFD）对气液固三相搅拌反应器的数值模拟仍属起步阶段。

| Abstract: | The progress of the research on hydrodynamics in gas-liquid-solid three phase stirred reactors in the last five years is reviewed.The hydrodynamic characteristics of hot-sparged multiphase stirred(reactors) is the focus of research in the last decade.Gassing power consumption,macro-mixing time,(local) and overall gas hold up in hot-sparged system are introduced.Solid-liquid suspension,gas-liquid mass transfer and the mechanisms of gas dispersion and solid suspension have not been investigated yet.Numerical simulation of hydrodynamic behavior of three phase stirred reactors by using the computational fluid dynamics(CFD) approach is still in the beginning. |
