Fouling Influence Factor Analysis of Axial Flow Compressor

Abstract:

Fouling is an important performance degradation factor of axial flow compressor. In order to reveal fouling mechanism, flow simulation of four cases of NASA rotor37 has been performed, such as clean compressor, compressor with roughness of 50μm, 100μm and 150μm. Thermodynamics performance parameters of compressor at different rotational speed with different roughness are discussed. And then fouling sources and its influence factor are analyzed. Research finds that gas contaminants can deposit in blade surface existed with internal oil and water. Simultaneously, humidity, temperature, flow velocity and contact area are the main factors for the formation of compressor fouling. Finally, research finds that fouling can easily formed in suction surface and fouling level of leading edge is more critical than other locations.
