Definition of a Screening Criterion for Centrifugal Compressor Vibrations Induced by Inlet Gas Flow
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 4: The gas flow entering from the inlet flange of a centrifugal compressor may induce radial forces on the rotor, by directly impinging onto shaft or by generating asymmetric pressure fluctuations in the gas volume ...
