The Performance Calculation Method of Fouled Axial Flow Compressor Based on the Stage Stacking Method

Abstract:

Fouling is the most important performance degradation factor, so it is necessary to accurately predict the effect of fouling on engine performance. This paper develops a performance calculation method of fouled multi-stage axial flow compressor based on experiment result and operating data. For multistage compressor, the whole compressor is decomposed into two sections. In this model, the performance of the first section is obtained by stage stacking method by combining scaling law method, linear progression model with traditional stage stacking method. On the other hand, the performance of the second section is calculated by averaged infinitesimal stage method. Finally, the model is successfully applied to predict the 8-stage axial flow compressor.
