Flow into a transonic compressor rotor: Part 1 - Analysis
Shreeve, Raymond P.
MetadataShow full item record
An analytical representation is given for the axisymmetric 2 -dimensional flow field at the face of a transonic rotor. Streamlines computed for irrotatational inviscid flow are closely approximated using a curve-fitting technique, which is described, and boundary layer blockage is then introduced. With the inlet flow so represented, the conditions relative to the rotor blading of the TRANSX compressor are calculated as a function of the radius and graphed as a function of flow rate and rotor speed. The purpose of this report is to both document calculations carried out for the TRANSX compressor and to record useful analytical techniques and short programs developed using the Hewlett-Packard Model 9830A Calculator.
