摘要
Abstract
Large-scale axial flow compressors are widely used in metallurgy,wind tunnels and other scenarios.Among them,this paper proposes a new method based on modular design and integrated optimization to scientifically optimize the flow channel structure of the compressor,significantly improve the aerodynamic efficiency and pressure ratio margin of the compressor,and solve the problem of stability and high efficiency of the compressor over a wide operating range.At the same time,numerical simulation technology is used to optimize the airflow uniformity in the inlet and exhaust chambers,reducing pressure losses.Experimental results show that the shaft vibration and displacement of the compressor are far lower than the alarm values,the speed control accuracy meets the design requirements,and the sealing performance is good.Based on the above research results,it is shown that the design method proposed in this paper can not only significantly improve the aerodynamic performance and operating stability of the compressor,but also accurately control the airflow parameters.The research results can be applied to the design and optimization of continuous transonic wind tunnels,providing reliable technical support for aircraft aerodynamic research.关键词
