摘要
本文以某双级对转压气机为研究对象,基于并行计算技术,用数值模拟的方法计算研究了进口导叶安装角对对转压气机性能影响规律,从机理上分析了设计流量下导叶调节对各叶排来流气流角影响,为对转压气机的进一步优化设计提供依据。计算结果表明:在现有计算机条件下,并行计算技术的采用大大提高了计算效率;进口导叶安装角对对转压气机性能有一定影响,当进口导叶向负方向调整时,转子1工作正攻角下,出口导叶工作于负攻角,压气机的增压比升高,效率基本不变,稳定工作范围略有增大。
In this paper,we investigate the aerodynamic performance and flow field of dual-stage counter-rotating compressor using the numerical simulation based on the parallel computation technique.The aim is to study the influence of the stagger angle of the inlet guide vane,which include the aerodynamic performance of the whole compressor and the inlet flow angle of each blade row.The result demonstrates:(1) computation efficiency is improved using the parallel computation technique based on three personal computers;(2) the stagger angle of IGV have an influence on the aerodynamic performance of counter-rotating compressor;(3) The inlet flow angle increases for Rotor 1 and decreases for OGV with adjusting IGV to the anti-clocking-wise,so the total pressure ratio is improved,efficiency is nearly constant and the work range is extended a little.
