Introduction to Radial Compressor Design
A detailed understanding of the aerodynamic behavior and structural integrity of centrifugal compressors is essential to meet competitive market needs. This course covers the fundamentals of radial compressor design along with the design process and analytical methods used to make state-of-the-art machines.
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. Trade-offs between peak performance, range, life, and cost will be covered. Special emphasis is placed on surge, choke, design methodology, and model development. All lectures are given by internationally renowned authorities.
