摘要/Abstract

摘要： 基于一维层流反应流模型,构建了新的准稳态均相模型,并对堆积床内充分发展后的低速过滤贫燃过程进行数值模拟.将计算结果与传统双相模型进行比较,分析弥散效应和化学反应机理等对计算结果的影响,并开展输运项分析;将均相模型的数值结果与准稳态和瞬态的理论结果进行比较,验证理论方法.

关键词: 堆积床, 过滤燃烧, 均相, 准稳态

Abstract: Based on a one-dimensional laminar reactive flow model,a new pseudo-homogeneous model is constructed and adopted in quasi-steady-state simulation of low-velocity filtration combustion in a packed bed under fully developed conditions.Influences of dispersion effect and reaction mechanisms are discussed in detail by comparsion of the conventional two-phase model with the pseudo-homogeneous model.Effects of various transport terms on different conservation equations are studied.The performance of quasi-steady-state and transient analytical solutions is evaluated by comparing with pseudo-homogeneous model.

Key words: packed bed, filtration combustion, pseudo-homogeneous, quasi-steady-state
