THE PHYSICS OF PULSATIONS - PART I: A Method to Provide Accurate Prediction of Pulsation Magnitudes Critical to Compressor Station Design

摘要

The principles of acoustics have been well studied over the last century because of the applicability of acoustic theory to the broad spectrum of noise-related engineering problems. In the design of piping systems for reciprocating compressors in the 1940s and 1950s, the simplest filter designs were derived from basic acoustic theory. Though some of the basic principles may be analogous, reciprocating compressor-induced pulsations are not equivalent to small pressure perturbations described by basic acoustic theory. When modeling and designing reciprocating compressor systems, distinguishing the pulsations, as distinctly different from acoustic waves, will result in a more accurate depiction of the pulsation amplitudes and the response of the piping system.
