摘要
采用叶排间掺混面模型，研究了多级跨音速风扇及压气机三维粘性流动数值模拟问题，利用ＬＵ－ＳＧＳ隐式算法使计算过程快速收敛，通过高分辨率格式改善跨音速流场中激波的分辨率。对某双级跨音速风扇及五级压气机流场进行了计算，双级风扇各状态的计算结果与实验数据吻合较好。
Numerical simulation of 3D viscous flows through multistage transonic fans and compressors was carried out with circumferential mixing model between adjacent blade rows. Computations provide rapid convergence by the use of LU-SGS implicit method. Resolutions of shocks in transonic flow field are improved with a high- resolution scheme. Numerical calculations were performed on a two-stage transonic fan and a five-stage compressor. The two-stage fan flow predictions show a good agreement with experimental data.
