In this paper, the Greitzer surge model was systematically analysed with the model compressor duct length Lc as the tuning parameter. The surge phenomenon is known to induce a serious risk to centrifugal compressor operation. The two-dimensional Grei

Unstable flow structures cause inevitable energy losses in all power energy systems, including turbomachines. In this study, a set of analyses was conducted with the use of spectral maps on the pressure signals obtained from an industrial centrifugal

This paper presents the universal method of assessing the Vaneless Diffuser Rotating Stall (VDRS) cells’ size with the use of the Particle Image Velocimetry (PIV) technique. Two different cell dimensions’ definitions were introduced: Radial Cell

This paper describes the vaneless diffuser rotating stall (VDRS) development and cell-merging phenomena. A centrifugal compressor’s lifespan may be limited by flow instabilities occurring in off-design operation. One such instability is the VDRS, w

This paper presents tests of an anti-surge system based on pressure derivatives. The control algorithm was proven to work on different machines and with different unstable flow phenomena. Compressors are known to be affected by unstable flow conditio

Wind energy as source of electricity has grown rapidly in the recent years. Consequently, a great variety of research on wind turbines impact on environment is necessary. It is worth to mention that notably the Small Wind Turbines gain on importance.

In this paper the flow recirculation regions during the full surge cycle were described. It is a known fact that the surge cycle consists of two periods: backflow and recovery. The aim of this paper is to add spatial dimension to this analysis. There
