Centrifugal Compressor Application Sizing, Selection, And Modelling.

Tutorialpg. 195-202The objective here is to build on the fan law paper presented at the Twentieth Turbomachinery Symposium [1]. The centrifugal sizing and modelling tutorial draws on the pseudo compressor stage curves presented in the fan law paper. The presenters will elaborate and demonstrate the effects of curve shape, gas properties, and other factors on stage matching. For comparison, fan law and actual section properties will be compared to help the ultimate practitioner with the decision of when various methods are reasonable and applicable. Estimating centrifugal compressor fit for a given application using manufacturer's catalog data will be covered, along with aerodynamic modelling of actual compressor hardware after purchase for monitoring of off-design, fouling, or potential rerating
