Cross-Scale Flow Field Analysis of Sealing Chamber and End Face Considering the CO2 Real Gas Effect
Sun, Xuejian; Song, Pengyun; Hu, Xiangping; Mao, Wenyuan; Deng, Qiangguo; Xu, Hengjie (Peer reviewed; Journal article, 2021)The dry gas seal (DGS) is a non-contacting, gas-lubricated mechanical face seal commonly used in rotating machinery. Traditional analyses of DGSs treat the end face as an independent factor by setting the end-face inlet ... -
Performance of Spiral Groove Dry Gas Seal for Natural Gas Considering Viscosity-Pressure Effect of the Gas
Sun, Xuejian; Song, Pengyun; Hu, Xiangping (Peer reviewed; Journal article, 2020)Centrifugal compressors used for transporting natural gas are usually equipped with dry gas seals. The working medium of the seal is usually the delivered gas, that is, natural gas. In this paper, the natural gas ... -
