Abstract: The applications of experiment and numerical simulation method on the research of rod baffle heat exchanger are reviewed，and their research achievements on the structure optimization of rod baffle heat exchanger are presented. Simulation has been used by more and more researchers with the development of computing technology，but computing devices of high performance are needed. Among the simulation methods，the applications of porous medium model，periodical unit duct model，periodical whole section model and the method of “simulate section by section，analyze integrally” are presented. The advantages and disadvantages of each method and model are analyzed，as well as their scopes of application. For different research purposes，different methods should be used. A combination of such methods and models can provide full information for researchers，including flow field，pressure field and temperature field，guiding the work of structure optimization of rod baffle heat exchanger correctly and effectively.

Key words: rod baffle heat exchanger, experimental method, numerical simulation, structure optimization

摘要： 综述了实验研究法与模拟研究法在折流杆换热器研究方面的应用，同时介绍了二者在折流杆换热器结构改进方面的研究成果。指出随着计算机技术的发展，模拟研究法越来越多地被研究者所采纳，但模拟过程对计算设备的要求较高。重点介绍了模拟方法中多孔介质模型、周期性单元流道模型、周期性全截面模型以及“分段模拟，整体综合”思想等模型与方法在折流杆换热器研究方面的应用，详细分析了各种研究方法与模型的优点、缺点及适用范围。对于指定的研究目的，应使用相应的研究方法或模型；各种方法与模型需要相互配合，取长补短，才能为折流杆换热器的研究提供全面的流场、压力场和温度场等信息，正确有效地指导折流杆换热器结构改进的研究工作。
