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.

Bifurcation analysis of a centrifugal compressor
2011 IEEE International Conference on Systems, Man, and Cybernetics, 2011This paper presents the local bifurcation analysis of the dynamic behavior for a centrifugal compressor. It is known that the surge phenomenon in compressor dynamics might occur at high pressure rise operation. Under such an operation, slight variation of the driving torque and/or the throttle opening might sharply reduce the compressor efficiency and ...

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 1998
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 ...

A S L E Transactions, 1977
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.

The Centrifugal (Radial) Compressor
1981The centrifugal compressor is one type of dynamic compressor, another being the axial compressor which is covered in chapter 6. As introduced in section 1.3, the dynamic compressor works by conversion of velocity to pressure in a continuous flow. This distinguishes it from the reciprocating compressor, which compresses the fluid intermittently in ...

FAILURES IN CENTRIFUGAL COMPRESSORS
Machine Science JournalCentrifugal flash gas compressors are mechanisms that convert the kinetic energy of gas into pressure energy, playing a crucial role in compressing and transporting associated gases in the oil and gas industry. These compressors operate on the principle of centrifugal force and are widely used in key industrial sectors.
