摘要
本文用k-ε紊流模型和可压缩流体压力修正方程以及SIMPLEC算法对时均形式的二维N-S方程进行了求解,得到了单腔室迷宫密封中的流场特性,其结果可以用来改进迷宫密封转子动力特性的分析模型.
In order to get the flow field in a labyrinth cavity, the finite-difference technique in connection with K-蔚 turbulence model is used to solve the time-averaged N-S equations; the pressure field is evaluated by using the compressible form of the SIMPLEC algorithm. The results can be used to improve theaanalysing model of labyrinth seal rotordynamic characteristics.
