Original abstract
The formation of aerodynamic instabilities during centrifugal compressor operation is undesirable due to reduction in efficiency and increased vibration and noise. Based on the measurement of noise and casing vibration of a centrifugal compressor, an analysis of the obtained parameters is made and the individual sources of vibration and noise are classified. Taking into account the worldwide research carried out in this field, it is possible to assign the selected frequencies to a specific phenomenon. The significance of the individual sources of noise and vibration can be assessed for selected operating conditions and the potential to reduce them can be analyzed as well.
