摘要

对气固循环流化床（CFB）提升管内的非均相流动行为进行了计算流体力学（CFD）模拟。基于CFD时均流场数据与信息，搭建了用于描述提升管内非理想流动过程的等效反应器网络（ERN）模型。在ERN模型建立过程中提出了反应器网络的6个拓扑结构参数和一个等效判据，并系统地分析了等效反应器网络结构六参数的性质与确定方法，从而形成了一套CFB提升管流动模型建模方法。

Abstract

Non-homogeneous gas-solid flow in a circulating fluidized bed (CFB) riser was numerically simulated with CFD models. According to the data and information obtained from the time-averaged CFD flow fields

a novel non-ideal reactor model named equivalent reactor network (ERN) model was developed for the CFB riser. Six parameters for characterizing the structure of a reactor network and the criteria for equivalence checking of the established reactor network were proposed. Systematic analysis on each model parameter and the correlations between them were made elaborately. Values of these parameters were determined subsequently. It was found that the developed ERN model

which was based on the time-averaged CFD flow fields

was capable of describing reasonably non-ideal gas-solid flow behaviors in the CFB riser.
