摘要
为了研究非稳态情况下直通型迷宫压缩机内部的流场特性,以4K-80MG机型为研究对象,根据其结构尺寸建立几何模型,依据非稳态分析中的动网格技术和活塞的实际运动规律,研究设计出控制活塞在气缸内运动的UDF程序,得出多种参数的分布云图和数据,能够真实地反映出气体在气缸以及迷宫齿间的流动情况,实现了实时观察迷宫内部流场特性。
In order to study the characteristics of internal unsteady flow field of straight type labyrinth compressor, the geometric model are established on the labyrinth seal structure of 4K-80MG labyrinth compressor. The movement UDF procedures of controlling piston can be designed by dynamic mesh technique and the actual movement of unsteady analysis, and the characteristics of internal unsteady flow field can be observed at any time.
