Description
Summary:The development of advanced turbomachinery relies heavily on the use of 3-D CFD methods. Fast and efficient 1-D and 2-D methods are used at early design stages in order to explore the design space of a new configuration. A new method has been developed to predict performance characteristics of axial-flow compressors in the following conditions: stable off-design; part-span and full-span rotating stall; reverse flow. The new method is based on the classical empirical 1-D method proposed by L.E. Olshteyn. An empirical model for a stall/unstall hysteresis loop has been developed. The developed method has been implemented in COMPRESSOR_S simulation software. The results for three stage axial compressor have been produced and compared against the experimental data published by Gamache.
