Dynamic effect of a pressure wave on a bypass pipeline of a compressor

Abstract

Under certain circumstances where there is a relatively great difference between inner pressures of output and input pipelines of a compressor, a so-called bypass pipeline is used to connect the pipelines of the compressor. When a control valve is quickly opened, the pressure difference generates a pressure surge that might affect the operational safety of the pipeline along which the pressure wave propagates. In this work dynamic effects of a pressure surge created in the bypass pipeline of one of the compressors of a transit gas pipeline are investigated using the finite element method.
