等空时双平推流循环流动的数学模型

摘要提出并解析了等空时双平推流循环流动的数学模型。结果表明,等空时双平推流循环流动模型的循环比 R 与其停留时间分布的无因次方差σ~2具有简单的数学关系,且满足流体返混的σ~2的一般判据。该模型除能较好地描述流体循环流动状况外,也可用于流体返混的流动模拟。

Abstract： Mathematical model of recycle tubular flow with equal space time is pro-posed in this paper.Results obtained from the model show that there is asimple mathematical relation between recycle ratio R and dimensionless varianceσ~2 of residence time distribution,and σ~2 is consis ent with the general criteriaof fluid backmixing.The model can be usel to describe fluil recycle flowas well as fluid baecmixing.
