Abstract
Taylor-Couette-Poiseuille (TCP) flow is prevalent in rotating machinery, occurring extensively between a high-speed rotating shaft and its static case. This study employed a numerical simulation method to investigate the flow characteristics and windage loss in supercritical carbon dioxide (sCO2) TCP flow. The findings revealed that increasing the rotational Reynolds number and aspect ratio and decreasing the axial Reynolds number and radius ratio reduced the friction coefficient (Cf). Ultimately, a Cf correlation for sCO2 TCP flow was derived through fitting simulation results, exhibiting an average relative error within ± 2 %. These results established a theoretical foundation for the structural design of sCO2 rotating machinery.
