Abstract: In this paper, a novel bulk-flow model for pocket damper seals (PDS) is introduced. The model is based on two control volumes (CVs) for each circumferential pocket of the seal. The continuity, circumferential momentum, and ...

Abstract: Flexure pivot® journal bearings (FPJBs) have typically been used in small high-speed applications such as integrally geared compressors and multistage high-speed compressors, where the temperature management and the ...

Abstract: The impact of sealing equipment on the stability of turbomachineries is a crucial topic because the power generation market is continuously requiring high rotational speed and high performance, leading to the clearance ...

Abstract: As well known, the stability assessment of turbomachines is strongly related to internal sealing components. For instance, labyrinth seals are widely used in compressors, steam, and gas turbines and pumps to control the ...
