Modeling tip clearance effects in multistage axial compressors
- Pratt and Whitney, West Palm Beach, FL (United States)
A variety of techniques for simulating the effects of rotor tip clearances in multistage axial compressors is discussed. Proper recognition of stage coupling and rematching effects is shown to be key to successful modeling of the overall behavior of actual engine compression systems. The application of a relatively simple one-dimensional unsteady row-by-row systems analysis is presented and shown to compare well to test data from several engine compressors.
