Detailed understanding of the aerodynamic behavior and structural integrity of centrifugal compressors is essential to meet competitive market needs. The student will learn the basic phenomena occurring in inlets, impellers, diffusers, volutes, and return channels. The entire development and design process from 1D to 3D viscous methods is taught while stressing preliminary cycle work, velocity triangle optimization, blade loading considerations, viscous flow field analysis, and structural analysis. Special emphasis is placed on surge, choke, and design methodology.

What You Will Learn

This course provides a survey of the design and analysis of centrifugal compressors. The objective of the course is to provide participants with:

  • An overview and familiarization of the design and operation of the complete machine, and individual components of the machine
  • A familiarization of the best design practices at all levels, from basic machine selection to the detailed aerodynamic and mechanical design of all components
  • A guide to the different types of computer-based analysis tools available, and the applicability of each
  • An understanding of how to achieve the best compromises between efficiency, range, cost, life, and durability.



The course materials have been developed over many years and are regularly reviewed to ensure that they are kept up to date. Course materials include the textbook, Centrifugal Compressor Design and Performance, written by Dr. David Japikse, as well as a memory stick of course notes.
