Theory and experiment on air flow field in bearing chamber

  • 摘要: 采用有限元数值分析和试验研究的方法,研究了航空发动机轴承腔气相介质的压力场和速度场,探讨了转子转速和密封进气量等工况参数对轴承腔气相介质压力和速度分布的影响规律,研究工作表明:轴承腔气相介质压力随着转子转速、无量纲径向坐标、密封进气量的增加而增高;气相介质无量纲切向速度随着转子转速增高而增大,随着密封进气量增大而减小.试验结果表明:随着转子转速和密封进气量的增加,气相介质压力的试验结果与计算结果吻合性均增高.通过计算和试验揭示出的工况参数对轴承腔气相介质压力的影响规律,有助于轴承腔气相介质流动物理特性研究的完整性.
