Abstract

The present work is devoted to the numerical study of dense gas flows in turbomachinery and the assessment of their interest as working fluids in energy-conversion cycles. A structured and an unstructured dense-gas solver are used to ensure the reliability of the computed results for dense gas flows through a turbine cascade. The physical analysis is focused on the effect of the working fluid and its operating thermodynamic conditions on turbine performance.
