The New Performance Calculation Method of Fouled Axial Flow Compressor [PDF]

open access: yesThe 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.
