Surges occur in compressor systems including turbo compressor at low flow rates. Surges not only degrade the performance of the compression system but can also damage the compressor system. There have been few studies on low-flow rate centrifugal compressors, and their dynamic characteristics are still unknown. In this study, the behavior and inception process of surges in a low flow rate centrifugal compressors were investigated. As a result, it was found that surges occur even in low flow rate compressors with small plenum, and that small pressure fluctuations that are precursors to the occurrence of surges occur.
