某型1.5级压气机试验与数值模拟研究的中期报告 【摘要】针对某型1.5级压气机设计和燃气轮机系统优化研究的需要，本文开展了压气机试验与数值模拟研究。试验采用全尺寸模型，通过测量压气机的各种参数数据，分析了压气机在不同工况下的性能表现及流场特征。同时，提取了试验数据用于数值模拟验证。 基于试验数据，采用CFD软件建立了某型1.5级压气机的数值模型，并通过数值模拟，进一步分析了压气机的气动性能及流场特征。模拟结果表明，压气机在高压约束下进行旋转运动时，其旋转流场存在较为明显的非定常现象，且压气机进口气流的旋转度对压气机的性能有显著影响。 【关键词】压气机；试验；数值模拟；流场；气动性能 【Abstract】In order to study the design and optimization of a certain type of 1.5-stage compressor and gas turbine system, this paper conducted experimental and numerical simulation research on the compressor. The full-scale model was used in the test, and the performance and flow field characteristics of the compressor under different operating conditions were analyzed through measuring various parameters of the compressor. At the same time, the experimental data was extracted for numerical simulation verification. Based on the experimental data, a numerical model of a certain type of 1.5-stage compressor was established using CFD software, and the aerodynamic performance and flow field characteristics of the compressor were further analyzed through numerical simulation. The simulation results show that when the compressor rotates under high-pressure constraints, there are obvious unsteady phenomena in the rotating flow field, and the degree of rotation of the inlet airflow has a significant influence on the performance of the compressor. 【Keywords】compressor; experiment; numerical simulation; flow field; aerodynamic performance.
