A Casing Treatment with Axial Grooves for Centrifugal Compressors

Thermoplastic Labyrinth Seals for Centrifugal Compressors

For over 15 years now, the efficiency and reliability of centrifugal compressors have been enhanced by the application of thermoplastic materials to the eye, shaft, and balance piston labyrinth seals. Traditionally these seals have been manufactured from metallic materials and have required relatively large clearances for reliability reasons. By upgrading to carefully selected engineered thermo...

A Comparison of Regenerative and Centrifugal Compressors

Rotating stall control for axial #ow compressors

Rotating stall is a primary constraint for the performance of axial #ow compressors. This paper establishes a necessary and su$cient condition for a feedback controller to locally stabilize the critical equilibrium of the uniform #ow at the inception of rotating stall. The explicit condition obtained in this paper provides an e!ective synthesis tool for rotating stall control. 2001 Elsevier Sci...
