The New Performance Calculation Method of Fouled Axial Flow Compressor [PDF]
The Scientific World Journal, 2014 Fouling is the most important performance degradation factor, so it is necessary to accurately predict the effect of fouling on engine performance. In the previous research, it is very difficult to accurately model the fouled axial flow compressor.

Stability of Flow Through Multistage Axial Compressors [PDF]
Volume 1: Turbomachinery, 1989 This paper describes measurements of the performance of a research stage operating in isolation and as part of a multistage compressor. It is shown that the stall point and the stalled performance of the stage are properties of the system in which it operates rather than a property of the stage itself. The consequences of this for the estimation of the

Flow Field Diagnosis in Multistage Axial Compressors [PDF]
Volume 1: Turbomachinery, 1996 A mathematical model is developed for the flow field diagnosis problem in multistage axial compressors. In view of the ill-posedness of the diagnostic problem, an effective measure is adopted to transfer the diagnostic problem into a variational problem which is solved by a regularization method. Two numerical results demonstrate the rationality of the
