Colwell, G T

A procedure is presented for the aerodynamic and thermodynamic design of centrifugal compressors. Design equations are derived from basic laws of thermodynamics and fluid flow where possible. The experimental data and much of the mathematical treatment comes from the extensive literature on centrifugal compressors. An attempt has been made to assemble the bits of information which were available into a logical design method. The available information has been supplemented with mathematical developments and explanations which seemed necessary to complete the general view of centrifugal compressor design. Of particular interest is the derivation, using the work of Stanitz and Ellis (NACA Report 954) as a starting point, of equations which provide for estimating the velocity distribution on the leading edge of an impeller vane. Also included is an example of an aerodynamic-thermodynamic design of an impeller and a volute- conical diffuser combination. All the ncessary staps are demonatrated, beginning with a set of basic compressor requirements and resulting in a layout of the impeller and casing. (auth)
