摘要：

研究混合器的停留时间分布对进一步研究混合器内的流型、混合等具有重要的意义。首先介绍了用于描述停留时间分布（RTD）的统计特征参量，根据测试原理及示踪剂输入方式等对停留时间的实验方法进行分类介绍。着重回顾了化学反应工程方法中RTD模型的发展，对有关RTD流场模拟中的常用模型进行了对比分析，并对统计学方法在RTD中的应用加以描述。最后展望了对上述方法在停留时间分布中的进一步应用。

Abstract:

It is important to study the residence time distribution in mixers for a better understanding of flow and mixing. The statistical parameters for describing the RTD are introduced and the different experimental methods for RTD are presented according to the measurement principles and different modes for tracer inputting. The developments of model simulation in chemical reaction engineering method for RTD and flow field simulations for RTD are described. Comparison analysis is made for the choice of different models in flow field simulation. Finally，the applications of statistical methods in RTD are discussed. Future research and development of RTD methods are discussed.
