活塞速度对迷宫密封性能影响的数值分析

Numerical Analysis of the Effect of Piston Speed on Labyrinth Seal

通过对迷宫密封机理的分析,利用流体力学原理建立数学模型并进行数值计算,得出了在速度变化情况下的气体泄漏规律。

Through analyzing the labyrinth seal mechanism and basing on the fluid mechanics principle,a mathematical model was built to find gas leakage rate while the velocity of pistol varies.
