If some one want to do off design simulations for variable geometry compressor engine in GasTurb , is it possible to see the performance of the engine at different kind of varying angles. Because as i know , GasTurb considers some default VG factors a, b and c with a=b=1 and c=0.01...The confusion here is , how to encounter different angles for VIGVs and VSVs..if it is possible , then can we get compressor map with designated angles....?
Dear Muhammad
Besides not being answer to your question, I do not know how to answer. We developed our own computer programs to deal with variable geometry compressors, turbines and propelling nozzles. These components are designed and their performances calculated using our own software. A set of compressor, turbine and propelling nozzles maps are synthesized (one each for different angles and interpolated for angles not covered in the maps). It is not difficult task, but takes time to develop, verify and certify every piece of software.
