Flow Analysis of Axial Compressor AV63-15 Variable Stator Simulation
This paper conducts numerical simulation to a 15-stage civil axial flow compressor and obtains its main parameters distribution and performance curve by a full three-dimensional viscid flow computation software.The computation result indicates that,the developed axial flow compressor meets the anticipated design requirements,and satisfies the customers indicators.Under the designed compression ratio,the difference between the maximum air supply quantity in summer and the minimum air supply quantity in winter is 22%.By comparing the operating conditions and data analysis,obtained the change trend of axial velocity,static pressure and temperature,and Ma,and discovered that,under opening of 48° and outlet back pressure of 550KPa,flow separation occurred on the section of machine set close to hud,which indicated that operating condition was close to surging condition.
