Experimental Investigation and Validation of High Cycle Fatigue Design Systems for Centrifugal Compressors.

Abstract (German)

Most of the compressive turbomachines in use for turbocharger and industrial applications are of the radial flow type. Manufacturers of centrifugal compressors operate in a very competitive international market and rely on newest technology in order to maintain and to improve their market share. This requires the continuous improvement of their technology. The scope of this project addresses blade vibration in a centrifugal compressor. The need for reliable data to advance the understanding of forced response in centrifugal compressors is one of the motivations for the proposed work. Secondly, there is a need to develop and validate computational tools to be used in the design process to guarantee mechanical integrity.
