Compressors have been an ongoing subject of study, with the main objective to outline the stable operating range of these turbomachines. The occurrence of instabilities known as rotating stall and surge limits this operating range. Such unstable phenomena induce a considerable drop of performance in terms of pressure ratio, efficiency and mass flow, also leading to serious mechanical failures. Consequently, a surge margin is usually imposed to prevent the compressor operation from these situations. Both the increase of the stable operating range and the decrease of the surge margin are crucial, and represent a real challenge for designers. Aeronautical and automotive industries keep developing innovative strategies to understand and control the instable phenomena in that purpose, and finally reach better performances under steady, unsteady and transient conditions.
This forum focuses on (i) recent avances in design and analysis methodologies and (ii) technological and scientific new challenges. The researchers and engineers are invited to share their experience and to confront their expertises and their opinions.
