摘　　要：对直通式迷宫密封的流场和泄漏量进行了分析。采用CFD方法,应用k-ε湍流模型,SIMPLE算法,计算了迷宫密封内的速度分布、压力分布及泄漏量。就旋转速度对低比压直通式迷宫密封泄漏量影响做了进一步的分析,对进一步理解迷宫密封的机理具有一定意义。An analysis on the flow and leakage of straight -through labyrinth seals was done. According the CFD technology, the velocity distribution, pressure distribution and leakage of the labyrinth seals were gained by means of k-ε turbulence model and SIMPLE algorithm. On the condition of low pressure ratio, a detailed analysis on the rotate speed which affect the labyrinth seal leakage was made. It can provide a further understanding of the labyrinth seal.
