In plant systems including high-pressure-ratio multi-stage axial compressors or gas turbines, transient flow phenomena and their influences on the system components caused by possible compressor surge should be critically examined. In the situation, the compressor internal working conditions, caused by stage stalling and affected by the transient flow-path conditions, will also give serious effects on the phenomena ; the fact has often been be neglected in the conventional analyses. This paper describes a practical method of compressor surge simulation over the transient behaviors both of the entire flow-path and the internal stages, in particular the latter on the basis of one-dimensional stage modeling and application of fundamental equations of mass, motion and energy.
