In the study of the general problem of predicting performance and instability of installed jet engines during water ingestion deliberate or accidental, the establishment of the behavior of the compressor in an engine is an important task. In continuation of an earlier study, this report includes a analysis of selected compressors with water ingestion and evaporation, b effect of bleed andor injection, and c further development of a two-phase model with three droplet sizes for calculating compressor performance. An important result of investigations on selected compressors is the crucial influence of the location of water evaporation in the compressor and the blade loading. A second significant outcome of the investigations is that in order to simulate the engine with two-phase flow component responses are required in great detail. Author
