• 817 Damping Characteristics of Pressure Pulsations in Piping Systems Induced by a Centrifugal Compressor

抄録

Damping of pressure pulsations in piping systems excited by centrifugal compressors or blowers at blade-passing frequency dominates acoustic resonant characteristics. In this study, the relation between the resistance coefficient of the compressor and the operating point was investigated experimentally. As a result, the resistance coefficient of the compressor depends on the Reynolds number defined by the equivalent velocity of the pulsating flow. It is shown that the pressure pulsations in piping systems can be evaluated by one-dimensional wave model taking into account the damping characteristics of the compressor.
