摘要
以CFD软件FLUENT为基本工具,应用有限体积法对流场进行数值模拟,同时采用了k-ε湍流模型,通过耦合与离散相结合的方法求解N-S方程,数值模拟迷宫密封内流场。对单腔和两腔直通式密封做数值模拟,得到了流量系数随进出口压差变化的曲线,与实验结果比较,显示FLUENT软件在数值模拟类似流动时是可靠的,最后分析了密封齿几何参数对流量系数的影响,由此提出改进方案并进行优化。
Fluent, which is one of the most popular software in Computational Fluid Dynamics, is used as the main tool of numerical simulation, the finite volume method （FVM） is used in Fluent. The turbulent model is k-ε equation, and When solving N-S equation, segregated method and coupled method are used together. After calculating by FLUENT, the flow field in labyrinth seal is obtained and compared to the result of experiment, which shows a good accordance. By analyzing the curves of flux coefficient to labyrinth seal＇s geometric parameter, a new design is put in and optimized.
