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. F...

In present work, a compressor configuration is taken from literature which will be studied for aspect ratio (ratio between length of blade to chord length) influence over performance. Performance in the sense is pressure ratio of compressor. The aspect ratio of the blade is an important parameter and has a strong influence on the performance of axial flow compressor. There are so many literatur...

Rotating stalls are one of the most dangerous phenomena to be avoided in designing and operating axial flow compressors. An understanding evolution characteristics around rotor tip region is important study process stall development. In this paper, some critical stall-related structures, which could not observed by traditional analysis methods, understood using proper orthogonal decomposition (...

Stable operation of both axial and radial compressors is constrained by the occurence of aerodynamic flow instabilities: rotating stall and surge. Developments in the understanding of the physics behind these instabilities and ideas of how t o stabilize the compressor system, have opened the door t o a new era in the field of compressor control. This study gives an overview of the current state...

In this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. For this purpose the 3-D unsteady Euler equations in cylindrical coordinate are averaged in tangential direction. Therefore, the equations are reduced to a 2-D system. By averaging the tangential component of momentum equation, a blade force will result. Axial and r...

A computational and experimental study was carried out to determine whether blade tip suction can increase compressor efficiency. Compressor flow fields contain concentrated regions of high entropy fluid near the blade surfaces. Blade suction can remove this fluid, lowering the entropy of the compressor throughflow, thereby avoiding a thermodynamic inefficiency, ultimately raising the compresso...
