Rotating Stall in Centrifugal Compressors -- CFD Online Discussion Forums

October 9, 2000, 10:27	Rotating Stall in Centrifugal Compressors	#1
Paul den Held Guest Posts: n/a	In my job we have just recently come across with the phenomena of Rotating Stall which was the source of shaft vibrations and pulsating flow from the discharge of one of the compressor. The vendor of the compressor was however not able to provide a CFD calculation of the flow in impellers and diffusors. My question basically is does any of you have experience in modelling Rotating Stall in centrifugal compressors, if so, can you send me some developed CFD results showing these vortices. (in JPG file please) Many thanks, Paul
