摘要

本文的研究目的是分析燃气涡轮发动机的直密封迷宫在静态和动态条件下的性能。研究了雷诺数和齿宽与叶尖间隙比(tw/C)对直密封迷宫性能的影响。对不同压力比(PR)和不同转速(RPM)进行了分析。计算结果与已有的实验结果吻合较好。

Numerical Analysis of flow in cavities of labyrinth seals

Objective of this study is to analyze the performance of a straight sealing labyrinth in gas turbine engines in static as well as dynamic conditions. The study contains the effect of Reynolds number and ratio of tooth width to tip gap (tw/C) on the performance of straight sealing labyrinth. The analysis was carried out for different pressure ratios (PR) and different rotational speeds (RPM). The results are in good agreement with the available experimental results.
