Using the lumped parameter Greitzer model, most compressor surge behaviors (for classic or deep surge) can be estimated. However this model is too simple, since, in general, the rotor flow passage length is longer for high-pressure compressors than that for low-pressure ones, and modern high-pressure compressors have a strong axial pressure gradient distribution in the flow passage. Dealing with the above, this paper is aimed towards suggesting a multielement model to which is applied Greitzer model for each element, and explaining the relations between the surge behavior and compressor flow field time constant, by comparing the results of Greitzer model and the experiments of the aircraft gas turbine with a relatively high-pressure compressor.
