Abstract EN
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.
This paper develops a new performance calculation method of fouled multistage axial flow compressor based on experiment result and operating data.
For multistage compressor, the whole compressor is decomposed into two sections.
The first section includes the first 50% stages which reflect the fouling level, and the second section includes the last 50% stages which are viewed as the clean stage because of less deposits.
In this model, the performance of the first section is obtained by combining scaling law method and linear progression model with traditional stage stacking method; simultaneously ambient conditions and engine configurations are considered.
On the other hand, the performance of the second section is calculated by averaged infinitesimal stage method which is based on Reynolds’ law of similarity.
Finally, the model is successfully applied to predict the 8-stage axial flow compressor and 16-stage LM2500-30 compressor.
The change of thermodynamic parameters such as pressure ratio, efficiency with the operating time, and stage number is analyzed in detail.
