Investigation on Surge in Centrifugal Compressors

A test bench for conducting compressor surge experiments is set up, and differen t system configurations formed by changing the length of compressor outlet pipel ine are tested for surge. Dynamic pressure signals relating to surges are acquir ed at different locations of the configurations using unsteady measurement & dat a acquisition system. The sliding window method is adopted to set up quantitativ e criterion on the surge. Parameters included in the criterion, such as location of data collection, size a...
