Axial-Flow Compressor Performance With Water Ingestion

Abstract

Stage-stacking computer code (WISGSK) developed for prediction of offdesign axial-flow compressor performance with water ingestion. Code uses meantime stage-stacking method; stage and cumulative compressor performance calculated utilizing representative triangles located at rotor inlet and outlet mean radii. Code provides options for calculation of performance with mixtures of gases such as air and water vapor and air/water droplet mixtures with different water contents. Useful for obtaining preliminary estimates of overall performance of compressors with water ingestion given design point details corresponding to airflow and nature of corrections for air/water mixture flow.
