| 摘 要： | 通过对刷式密封的刷子中泄漏流动特点的分析,可以把刷子当作多孔介质来处理,从而建立刷子多孔介质的泄漏流动模型,这样可以简化刷子中复杂的泄漏流动,便于计算工程实际密封中环形刷子的泄漏量。

| Abstract: | In order to simplify the complex leakage flow in a brush and make it easy to calculate in real circular brush seal,a porous mdeium leakage flow model is established by means of characteristic analysis of the leakage flow in the brush.The numerical model is reasonable and practicable because the calculated results show a good agreement with experimental data. |
