Numerical simulation and analysis of steady-state performances for face and cylinder gas film seal system

  • 摘要: 针对端柱面组合气膜密封系统建立稳态特性的分析模型,给出基于有限元数值方法求解气膜压力分布的数值模拟方法和流程,实现端面、柱面区域的耦合求解,进而给出了端柱面组合气膜密封系统稳态特性数值模拟计算的方法.通过与Fluent软件仿真结果的比较验证数值模拟方法的正确性.重点研究膜厚与旋转轴转速对端柱面组合气膜密封系统稳态特性(端面气膜反力、柱面气膜反力、泄漏量、摩擦转矩)的影响,计算分析表明:随着膜厚的增加,泄漏量增加、摩擦转矩减小;随着端面膜厚的增加,端面气膜反力缓慢减小、柱面气膜反力出现极值;随着柱面膜厚的增加,端面气膜反力和柱面气膜反力都在减小;柱面膜厚对稳态特性的影响大于端面膜厚.端柱面结构中密封气膜压力的耦合对密封特性影响显著,稳态特性数值模拟方法的实现为动态特性分析提供了基础.
