Centrifugal compressors are used in a wide range of applications in which performance and mechanical integrity are invariably among the paramount design objectives. There is therefore continuing interest in the development of a sound understanding of the relevant physical phenomena and in the systematic application of the knowledge base that is the ...

Compact diffusers for centrifugal compressors
16th Joint Propulsion Conference, 1980The smaller centrifugal compressor diameter of many advanced turbofan engines renders unattractive the use of conventional conical or channel diffusing systems to deliver low Mach number, low swirl flow to the combustor. A method has been developed for designing a set of low-diameter, radially-emanating, controlledcontour passage diffusers.

A new impeller-to-sump seal was developed for a line of hermetically sealed centrifugal compressor units. Tests, using an actual compressor unit, were made to simulate steady operating conditions. Both new seal configurations and the original seal were tested. A new seal configuration resulted in a 25:1 reduction in refrigerant leakage.

CENTRIFUGAL COMPRESSORS CONTROL CRITICALITY
International Journal of Engineering Applied Sciences and Technology, 2023This article focused mainly on the importance of anti-surge control of compressor and how to design the recirculation line for turndown of compressors that’s referred as surge.

Hyperbolically shaped centrifugal compressor
Journal of Thermal Science, 2003Starting from the classical centrifugal compressor, cone shaped in meridional cross section, two modifications are considered on the basis of results from 2D and 3D flow models. The first modification is the change of the meridional cross section to hyperbolically shaped channel.

Centrifugal Compressor Surge Behaviour
Volume 1: Turbomachinery, 1984The unsteady behaviour of compressor systems near the surge line and during surge was investigated. Experimental examinations were carried out using a three stage centrifugal compressor of industrial design in different types of piping systems. The results obtained were compared with different theoretical models.

Sound generation in centrifugal compressors
Journal of Sound and Vibration, 2006Abstract An experimental study is described to explore the dominant sound generation mechanisms of the spectral components governing the overall noise level of centrifugal compressors. At the design speed with supersonic flow conditions in the rotor blade channels, blade tone noise and buzz-saw noise are the main contributors.

Centrifugal compressor performance prediction
World Pumps, 2016Data presentation is one of the main difficulties for the analysis of centrifugal compressors operative performances. However, actual performance is strictly related to field inlet gas conditions. Cmap software is designed to evaluate performance and predict the machine performances under different operative conditions.
