Modeling of a Novel Elastohydrodynamic Seal for sCO 2 Power Cycles With Experimental Verification
Available to Purchase
Proc. ASME. POWER2024, ASME 2024 Power Conference, V001T06A006, September 15–18, 2024
Publisher: American Society of Mechanical Engineers
Paper No: POWER2024-138553
... Abstract Effective sealing remains to be one of the technological challenges at the subcomponent level for supercritical carbon dioxide (sCO 2 ) power generation to be practical. Leakages from sCO 2 power cycles can lower cycle efficiencies by up to 0.65%. Therefore, to fully harness...
