Modeling and Simulation of Surge Phenomenon in Natural Gas Pumping Compressor Line

The paper proposes a technique for modeling a surge — the compressor line self-oscillating operational mode. The technique of constructing gas-dynamic characteristics of centrifugal compressors, artificially extended to the area of low flow rates, is described. The paper offers an example of computer simulation of the surge phenomenon in a natural gas pumping compressor line for the case when the operating mode is within the ascending section of the gas-dynamic characteristic plot.
