Experimental and numerical investigation of blade resonance in a centrifugal compressor for varying gas properties

Experimental and numerical investigation of blade resonance in a centrifugal compressor for varying gas properties

The blades of centrifugal compressors are exposed to unsteady forces during operation which can result in resonance response conditions and failures due to high cycle fatigue. A typical source of excitation is the unsteady fluid structure interaction between the impeller blades and the downstream va...
