| 摘 要： | 对多级轴流压气机叶栅内三维紊流流场进行数值模拟,采用高精度高分辨率的三阶ENN格式以保证对激波的捕捉和对紊流特征的正确模拟,利用LU-SGS隐式解法提高了计算速度,从而构成了一种既准确又高效的多级跨声速轴流压气机紊流流动数值求解系统。重点研究了动静网格的交接方法及相应的动静交接面处理模型。计算了某带进口导叶的三级轴流压气机,计算结果与实验数据吻合较好。

| Abstract: | Numerical simulation to three-dimensional turbulent flow in multistage axial compressor blade row is carried out,where high resolution third-order ENN scheme is adopted to catch the shockwave and simulate the turbulent flow correctly,and LU-SGS implicit method is chosen to improve computation rate.A nicety and high efficiency numerical simulating system is thus constructed.Central investigation is focused on the grid connecting methods between rotor and stator and the corresponding treatment for rotor-stator interactional surface.The final results for a three stages axial compressor with inlet guide vane show good accordance with the experimental data. |
