ABSTRACT To reveal the inner flow and sealing properties of a crenellated labyrinth seal, the CFD and experimental method are utilized, and the following research on this subject has been done: 1 Based on the referances, the status of labyrinth research is reviewed, the cause of key problem has been analyzed and the methods to solve the problems have been put forward.

本文以锯齿型径向迷宫密封为研究对象，以揭示密封内部流动规律及其与密封性能的关系为目的，应用计算流体力学与实验相结合的研究方法，完成了如下几方面的工作： 1 在文献阅读的基础上，指出了迷宫密封研究的现状、存在的问题和解决问题的途径。

The flow field in the axisymmetric crenellated radial labyrinth seal is simulated by the present numerical scheme, which emphsizes on examining the influence of relative teeth engaging length τ/T on the sealing property. It is found that the sealing property is firstly improved with the increase of engaging length, and becomes worse as the τ/T further increase, thus an optimal τ/T is existed.

对锯齿型径向迷宫密封的内部流场进行了数值模拟，重点研究了齿啮合长度对密封性能的影响及其流体力学本质—射流偏转，确定了最佳齿啮合长度，并讨论了啮合不对中、向内和向外流动对密封性能的影响等。
