Pipeline Pumping and Compression Systems: A Practical Approach, Second Edition
11 Pulsation and Vibration Analysis of Compression and Pumping Systems
Download citation file:
Flow and acoustic phenomena associated with various mechanical components in compressions and pumping systems have been the subject of considerable effort over the past few decades [1–15]. Research efforts concentrated on three main topics: (i) pulsation transmission characteristics of various pipeline elements, such as orifice plate, valves, compressors and branches; (ii) pulsation generation whether it’s flow-induced or resulting from reciprocating machines; and (iii) methods to suppress these pulsations by means of passive elements (such as pulsation bottles, mufflers, Helmholtz resonators, or side branch resonators) or actively by active control (e.g., active control of incipient surge in centrifugal compressor). Flow-generated pulsations...
