centrifugal compressor design and performance pdf

Centrifugal compressors are used in a wide range of applications in which performance and mechanical integrity are invariably among the paramount design objectives. A major challenge to the successful full-scale development of modern aerospace systems is to address competing objectives such as improved performance, reduced costs, and enhanced safety. Centrifugal compressors are used in a wide range of applications in which performance and mechanical integrity are invariably among the paramount design objectives. They achieve a pressure rise by adding kinetic energy/velocity to a continuous flow of fluid through the rotor or impeller.This kinetic energy is then converted to an increase in potential energy/static pressure by slowing the flow through a diffuser. 3 shows the passage areas of reference, normalized by the passage area of the impeller inlet.
