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.
