Multiphase Computational Fluid Dynamics Modeling of External Oil Flow From a Journal Bearing (2018)
Journal Article
Berthold, M., Morvan, H., Jefferson-Loveday, R., Young, C., Rothwell, B. C., & Ambrose, S. (2019). Multiphase Computational Fluid Dynamics Modeling of External Oil Flow From a Journal Bearing. Journal of Engineering for Gas Turbines and Power, 141(5), 1-12. https://doi.org/10.1115/1.4041517

High loads and bearing life requirements make journal bearings a potential choice for use in high power, epicyclic gearboxes in jet engines. Particularly, in a planetary configuration , the kinematic conditions are complex. With the planet gears rota...
