Résumé

This work describes a fast 2-D design methodology for supersonic axial Organic Rankine Cycle (ORC) turbines. A Method of Characteristics (MOC) generalized to gases governed by complex equations of state (EOS) is used to generate both stator and rotor blades. A steady viscous numerical simulation of a turbine stage designed using the proposed methodology is carried out by using the ANSYS CFX solver. The results show that the viscous effects represent the main source of isentropic efficiency drop, since the accurate MOC design allows to minimize losses due to shock waves.
