abstract

A deterministic approach for troubleshooting in axial multistage flow compressors, that is to say, the solution of the diagnostic or inverse problem is presented.

The approach utilizes a model which is capable of predicting the compressor performance with and without faults — solution of analysis or direct problems — previously developed and tested in several applications. The diagnostic problem solution, where the actual compressor performance is known, allows the type, level and position of a fault to be determined.

The novel method is presented and described in detail. The possibility to integrate this deterministic approach with heuristic diagnostic procedures, to take into account more complex fault configurations, is also discussed.
