摘　　要：本文在引入新型气油两相流粘度模型的基础上,建立了一套适用于气油两相流工况下滑动轴承的数值计算理论,计算研究了气油两相流对滑动轴承油膜刚度的影响,得出了一系列有益的结论。In this paper, a numerical method applying to journal bearing lubricated with bubbly oil was established by use of a new bubbly oil viscosity model, and its influences on the oil film rigidity of journal bearing were studied. Some useful conclusions were obtained.
