A Stage-Stacking Simulation of Axial Flow Compressors with Variable Geometry

摘要

Since most high performance axial flow compressors in development today have variable geometry, it is highly desirable to have the capability to evaluate various stator schedules as to their effect on compressor performance using computer simulation. The computer program covered in this report uses the 'stage-stacking' method of analyzing compressor performance and uses input derived from test data in lieu of detailed design information. It can accomodate compressors with up to 15 stages, 10 of which can have variable stators. In addition to providing individual stage performance and overall compressor performance in a printout format, the program also contains a plotting routine for displaying the overall compressor map in graphical form.
