In order to deal with the current economical and environmental context, the next engine generation will need to offer great operability, compactness and high efficiency. In aircraft engines, the compressor remains one of the critical components, and its design is still a challenging task. At low massflow rate, their operability is bounded by the surge limit, surge being a highly unstable and dangerous phenomenon. Today, few experimental studies on compressor surge are available because of the inherent threat to the facility. In that context, numerical simulation can bring about information on the onset of aerodynamic instabilities and help to predict the surge limit. The work presented in this PhD thesis aims at setting up a method to perfo...
