摘要：
The gas pulsation in reciprocating compressor piping systems would result in piping system vibration. Experiments and numerical simulation were performed to study the gas pulsation at the key positions of a piping system with two reciprocating compressors operating together. The fluid dynamics of the piping system was modeled with appropriate boundary conditions proposed. Both the laminar and turbulent flow models were employed to analyze the gas pulsation in the piping system. The comparison between the numerical results and the test data shows that the turbulence flow model is more reasonable than the laminar flow model. Further, three different turbulence models were used to investigate the gas pulsation characteristics and pressure non-uniformity. By comparing the numerical results with the experimental data, it is indicated that the standard k-ε turbulence model is most effective in simulating the gas pulsation of the piping system, and it would be suitable to the research on the influences among different pipelines and gas pulsation change with compressor speed in different pipelines when two reciprocating compressors operate together at different speeds.
