Windage and Leakage Losses in Impeller Back Gap and Labyrinth Seal Cavities of Supercritical CO<sub>2</sub> Centrifugal Compressors

The windage loss in impeller back gap and labyrinth seal cavities significantly impacts the aerodynamic performances of supercritical carbon dioxide (sCO<sub>2</sub>) compressors. To accurately calculate windage loss, essential factors affecting the skin friction coefficients <i>C&...
