Predicting the optimum design of single stage axial expanders in ORC systems: Is there a single efficiency map for different working fluids?
78
TL;DR: In this paper, the authors provide a design criterion of axial flow turbines which gives a reliable estimate of their efficiency for a wide range of operating duty specifications and working fluids, and a generalized efficiency map is obtained which can be easily integrated into a comprehensive thermodynamic cycle analysis and optimization to account for the real turbine performance.
