Abstract:The change of the outlet number of bearing chambers can change the pressure distribution in the chamber and the
action of the air shear force, which has an important influence on oil/gas two-phase flow and heat transfer. In this paper, the flow and heat transfer characteristics in the ventless bearing chamber and the vented bearing chamber were compared and analyzed by numerical simulation. The accuracy of the numerical model was verified by comparison
with the experimental data. Three different rotor speeds w… Show more
