A Moore-Greitzer model of a wet compression system was set up, which can be used to analyze the effect of wet compression on the post-stall transient response of a compression system. The simulation results of the model, qualitatively describing the effect of wet compression on the unstable operation performance of the compression system, indicate that under certain conditions the wet compression is conducive to eliminating surge and rotating stall. As a result, the operation stability of the system is enhanced along with an improved performance of the compressor, compression system and gas turbine.
