摘要

熵生成分析——本专题中描述的研究主题——是一种潜在的分析技术,正在开发中,以提供一种有用的方法来增强迷宫密封的功能和完善其结构。与传统技术相比,该方法旨在对迷宫密封中的能量耗散现象进行更基本的分析,并对不同流动区域的能量损失进行定量描述。本文的第一部分主要介绍了相关研究的方法和数值结果。第二部分将出现在即将出版的《密封技术》杂志上,将继续介绍如何应用该技术。

Entropy generation analysis technique for labyrinth seals – Part 1
Entropy generation analysis – the subject of the study described in this feature – is a potential analytical technique that is being developed to provide a useful way of enhancing the functionality of labyrinth seals and perfecting their structure. Compared with conventional techniques, the approach aims to provide a more fundamental analysis of the energy dissipation phenomenon in labyrinth seals and a quantitative description of the amount of energy lost in various flow regions. The first part of this article, which appears here, mainly looks at the approach and numerical results of the associated research. The second instalment, which will appear in a forthcoming issue of Sealing Technology, will continue coverage by explaining how the technique may be applied.
