Damping in Dense Gas Acoustic Structure Interaction

J. P. M. Smeulers [1], H. P. Pereboom [1], N. González Díez [1],
[1] TNO, Delft, The Netherlands

Large centrifugal compressors, which are commonly applied in the oil and gas and in the process industry, may fail due to vibrations of the impeller. These vibrations are induced by pressure pulsations in a compressor stage. These vibrations can be especially strong in so-called dense ... En savoir plus
