Abstract: Compared to traditional labyrinth seals, large-diameter (about 24 in or 609.6 mm) film-riding face seals are worth 0.55–0.65% points efficiency for utility-scale supercritical carbon dioxide (sCO2) turbines. Conventional ...

Abstract: A common issue associated with gas bearing–rotor systems is the tendency to generate self-excited vibrations, leading to instability. To address this problem, the fluid–structure coupling model of an aerostatic bearing–rotor ...
