A Post-Stall Compression System Modeling Technique
Abstract
This report presents a one dimenstional, stage by stage compression system modeling technique capable of exhibiting post stall behavior such as surge and rotating stall. Included is a brief overview of previous efforts by others, their major contributions and how the present effort enhances and extends these efforts. The modeling techniques, governing equations, numerical simulation, and stability criteria are all discussed. The model is validated by comparing it with a multitude of experimental test results from low-speed and high-speed compressor rigs and engine test results. The model provides an analysis tool for analyzing compression system and individual stage behavior during surge and rotating stall. Because the modeling technique is based upon stage characteristics, stage modifications can be analyzed for their affect on recoverability. Keywords: gas turbine engines; compression systems; component performance; rotating stall; surge; mathematical modeling.
