An investigation has been carried out to assess the effect of volute design on the performance of a centrifugal compressor. Three volutes, based on a turbocharger compressor volute, have been fabricated and tested. These volutes provided two that were larger than the original design, and one that was smaller. The alternative volute designs were fabricated from sheet steel and had a square cross...

surge and rotating stall phenomena are two dynamic instabilities that occur in both axial and centrifugal compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressing surge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. this resear...

The paper presents the first experimental performance data for a mid-stage centrifugal compressor test rig built at RWTH Aachen University. The results provide an analysis of the operational and loss behavior and will be published in an open test case for validating numerical methods. The test rig was built to investigate the operational and loss behavior of a complete return channel in detail ...
