Centrifugal compressors are widely used in different fields. Their design requires high
performance and a wide operating range, where, at lower mass flow rates, unstable flow …

Centrifugal compressor machinery is subject to a potentially damaging phenomenon called
surge at low mass flow rates. This effect may be preceded by a phenomena known as inlet …

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 …

In this article, a numerical model of the full surge cycle is presented for the low-speed
centrifugal blower and compared with the experiment. Surge phenomenon is very …

Purpose The paper aims to present an outline of the technology of the active anti-surge
algorithm based on high-frequency pressure measurement. The presented system is fast …

This paper presents tests of an antisurge system based on pressure derivatives. The control
algorithm was proven to work on different machines and with different unstable flow …

Centrifugal compressors are used in a multitude of industrial applications, and their reliable
operation is critical in all fields. In order to enhance stability, different methods are available …

This research paper presents an investigation of the local flow instability known as inlet
recirculation in a high-speed industrial centrifugal compressor. This phenomenon might …
