Modelling compressible multiphase flows [PDF]
ESAIM: Proceedings, 2013 Summary: We give in this paper a short review of some recent achievements within the framework of multiphase flow modeling. We focus first on a class of compressible two-phase flow models, detailing closure laws and their main properties. Next we briefly summarize some attempts to model two-phase flows in a porous region, and also a class of ...

Numerical analysis of aerodynamic lubricated double-decked protuberant foil thrust bearing
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2019 Double-decked protuberant foil bearing is a type of foil bearing that uses two stacking-up layers of protuberant foils as supporting structure. In preliminary experiments, wear failure of foil thrust bearing occurs occasionally due to excessive axial ...
