摘要

In order to analyze the influence of the change of axial position on the performance of labyrinth gear, the Fluent is used to simulate the airflow in the labyrinth in this paper. The leakage coefficient and heat transfer coefficient of the sealing teeth under different axial positions are obtained. The comparisons of results shows that the change of the axial position of the stepped labyrinth seals and the bushing has little effect on the airflow inside the cavity, and the change of axial position has little influence on the leakage coefficient of labyrinth seal; The change in the axial position of the stepped labyrinth seals and the bushing does not lead to a significant effect on the heat transfer characteristics of the airflow and the cavity channel.
