摘　　要：利用三阶ENN格式以及LU-SGS隐式解法,发展了多级轴流叶轮机械内流场的数值计算程序,重点研究了叶排间网格处理以及参数传递的方法。对某两级风扇叶栅内流场进行了数值计算,计算结果表明:该数值计算方法精度和分辨率较高,能够捕捉到叶栅通道内的三维曲面激波;计算速度较快,流量及流场参数残差收敛较好;设计点总特性计算结果与试验值基本吻合,满足工程精度需求。A numerical calculation program for inner flow in multistage axial turbomachinery is developed by applying threeorder ENN scheme and LU - SGS implicit method. Central investigation is focused on the grid connecting methods between rotor and stator and corresponding treatment for parameters interaction. Final results of a two stages fan show that： The developed method has high order accuracy and high resolution and can catch three dimensional shockwave correctly. Computation rate is very fast. Overall characteristic results show good accordance with experimental data.
