Abstract

Supercritical carbon dioxide power cycle can reduce the power consumption and achieve higher system efficiency with the properties mutation phenomenon of supercritical fluids near the critical point. Turbine is the critical component of the heat-work conversion in cycle which has advantages of compact structure, small size and so on. It has significant engineering values for its design. In this study, based on one dimensional flow, the RNG k-epsilon turbulence model was used. The supercritical carbon dioxide turbine nozzle and impeller were designed preliminarily, and the three-dimensional flow model was established. The detailed parameters of the aerodynamic performance were obtained. The results are expected to provide the appropriate design scheme and reference data for the engineering application of the supercritical carbon dioxide turbine and power cycling system.
