This paper shows experimental results obtained from a T100 microturbine connected with
different volume sizes. The activity was carried out with the test rig developed at the …

Time frequency analysis of the surge onset was performed in the centrifugal blower. A
pressure signal was registered at the blower inlet, outlet and three locations at the impeller …

Noise reduction in various industrial and building systems such as ventilation ducts,
vehicles, wind tunnels, and test facilities for jet engines, automobiles, and factories has …

Centrifugal compressor efficiency is the key to increasing incomes from its operation. There
are several flow instabilities which can negatively affect a compressor, one of them being the …

Methods of dynamical system analysis were employed to analyze unsteady phenomena in a
centrifugal blower. Pressure signals gathered at different control points were decomposed …

To obtain a high temporal resolution of mass flow data, a flowmeter based on the differential
pressure method has been developed. It is capable of detecting negative flow for …

The article is devoted to the experimental investigation of the interactions between the
amplitudes and frequencies of surge in a single-stage centrifugal blower and the …

The paper outlines the results of a numerical analysis of a low-speed centrifugal compressor
operating at design and off-design conditions. This included the analysis of surge …

The paper focuses on experimental investigation of the influence of outlet network volume
and type on the course of surge in a single-stage low-speed centrifugal compressor. The test …

The study aims to work out a set of recommendations for setting a proper distance between
the trailing edge of impeller and the interface boundary, which on the one hand would not be …
