摘要

根据杆栅支撑纵流壳程换热器的结构特点对其进行简化，建立了周期性单元流道模型，应用CFD软件FLUENT对不同介质、不同Reynolds数、不同折流栅间距时的模型进行流动和传热的模拟、分析与比较，获得了流道内流体流动和传热的细观特征以及折流栅间距的最优取值范围，为纵流壳程换热器的研究和应用提供了一定的参考.

Abstract

In the paper

the rod baffle heat exchanger with longitudinal flow of shellside fluid is simplified according to its structural characteristic and the periodic unit duct model is established.By employing commercial CFD software FLUENT

the numerical simulation of models for different media

at different Reynolds numbers and different rod-baffle pitches was carried out.The results were analyzed and compared to obtain the detailed characteristics of fluid flow and heat transfer in the duct and the optimal range of rod-baffle pitch values

which provides some reference for the research and application of heat exchanger with longitudinal flow of shellside fluid.
