随着生产更高效传热设备的不断努力，越来越多的增强表面正在商业化生产。因此，由于目前文献中测试数据的呈现方式多种多样，设计人员在比较和评估各种表面的性能方面面临着几乎艰巨的任务。因此，需要一种统一的格式来呈现增强表面的压降和传热数据。本文关注这一问题的一个重要方面，即管壳式换热器中使用的管状增强表面的问题。作为第一步，该主题仅限于单相压降和传热；然而，管程和壳程流量都被考虑在内。给出了可考虑用于管壳式换热器的商业增强管的综合列表，以及文献中可获得的性能数据的调查。提出并讨论了一种标准化数据格式，该格式使用内包络线和外包络线直径作为呈现所有管状增强表面的各种几何、流动和传热参数的基础。
As the efforts to produce more efficient heat transfer equipment continue, an increasing number of augmented surfaces are being produced commercially. Consequently, the designer faces an almost overwhelming task in comparing and evaluating the performance of various surfaces because of the many different ways in which the test data are currently presented in the literature. Thus, a uniform format for presenting pressure drop and heat transfer data for enhanced surfaces has become a necessity. This paper is concerned with one important aspect of this problem, namely, that of tubular enhanced surfaces used in shell-and-tube heat exchangers. As an initial step, the subject is limited to single-phase pressure drop and heat transfer; however, both tubeside and shellside flow are taken into consideration. A comprehensive list of commerical augmented tubes which may be considered for use in shell-and-tube exchangers is given, along with a survey of the performance data which are available in the literature. A standardized data format which uses the inside and outside envelope diameters as the basis for presenting the various geometrical, flow, and heat transfer parameters for all tubular enhanced surfaces is proposed and discussed.
