The method provides two levels of evaluation (i) whether the centrifugal compressor is stable or unstable and (ii) if unstable, whether it is a local instability (i.e. inlet recirculation) or a global instability (i.e surge). According to this definition, the surge margin may reach 20% for axial flow compressors of the turbojet and 10% for centrifugal machines. A good understanding of the physical mechanisms related to aerodynamic instabilities is an essential step in order to reduce the margins and improve the performance of compressors. The centrifugal compressor is a non-positive displacement type. It raises the pressure and temperature of the refrigerant by converting kinetic energy into pressure.
