Centrifugal Compressor Design and Performance
The course is both a state-of-the-art review of the technology base for these machines and also a practical guide for designers and application specialists. The range of application of centrifugal compressors is very wide, and their design and use is an important engineering industrial activity. Each area of application brings its own requirements to compressor design. Requirements of range, durability, and cost may compromise an efficient aerodynamic design, and must be recognized and accommodated in the design process. All these issues are addressed during the course.
The course begins with a thorough review of centrifugal compressor technology and one-dimensional design optimization. The level of confidence in stage analysis, using the best current data and models, is discussed and illustrated.
The design process is described in depth, including presentations of quasi-three-dimensional flow field calculations to predict loading levels, and 3D inviscid and viscous calculations for flow field prediction and design optimization. The use of CFD for compressor design optimization is shown.
Participants earn 2.7 Continuing Education Units (CEUs).
