用空气－柴油对ＴＥＭＡ－Ｆ型管壳式换热器模型在纵向折流板垂直放置下进行试验，得出相应的流型图和流型转变边界方程。研究表明，纵向折流板垂直放置时的流型图与纵向折流板水平放置时有较大差别。文内对纵向折流板放置位置对流型影响的机理作出了分析和解释。
The model of TEMA-F tube-and-shell heat exchanger was tested under the vertical baffle with air-diesel oil, and the corresponding flow pattern and flow transition boundary equation were obtained. The research shows that there is a big difference between the flow pattern when the vertical baffle is placed vertically and when the vertical baffle is horizontally placed. The paper analyzes and explains the mechanism of the convectional influence on the location of vertical baffle.
