Centrifugal compressors have been used in many areas of the machinery. The centrifugal compressor design is very complex, and a unique design system needs to be developed. A centrifugal compressor design system should be easy to use in interface and also flexible for inputs and outputs. The design tool also needs to be able to predicate the compressor performance in a fairly accurate level. In this study, a centrifugal compressor design system which was developed in the past is further improved and developed. Current design system includes initial parameter studies, meanline analysis, throughflow calculation, impeller design, diffusser design, volute design, and structure analysis. The main improvements of the design system are adding the interface to allow users easy to use, adding the input and output capabilities and modifying few correlations. Current design system can predict the blade loading and compressor performance better compared with original design system. A fuel cell low flow and low specific speed centrifugal compressor is designed by using current design system and the prototype compressor is built. The compressor performance tests were conducted. The experimental results are compared with numerical analysis. The experiments are in good agreements with calculations. The results demonstrate that the centrifugal compressor design is successful and the design system can be used for the future centrifugal compressor designs.
