为了探索对转压气机流场特性,在前后级转子等转速压比和效率特性试验基础上,在一个两级对转轴流压气机试验台上进行了前后级转子不同转差下的特性实验,并对试验工况进行了数值模拟,辅助分析了转差对压气机特性及流场的影响,数值模拟与实验结果符合较好.结果表明,转差变化引起压气机性能与流场结构发生显著变化,是影响压气机性能的主要因素之一.
In order to explore the flow field characteristics of the rotary compressor, based on the experiments of the speed-pressure ratio and efficiency characteristics of the front and rear stage rotors, a two-stage test on the axial-flow compressor was carried out to test the characteristics of the rotor at different slip angles , And the experimental conditions were numerically simulated to assist the analysis of the slip on the compressor characteristics and flow field, the numerical simulation and experimental results in good agreement with the results show that the slip caused by changes in the performance of the compressor and flow field structure Significant changes in the performance of the compressor is one of the main factors.
