摘　　要：本文用近似因式分解交替方向隐式格式直接求解叶轮机械中原参数三维不可压Euler方程组。在连续方程中引入“拟压缩性”之后,将原来类型不确定的控制方程变成双曲型方程,给定初边值之后用时间推进法求得稳定解,对一个单级压气机转子内部流场进行了计算,结果与实验值比较符合。Using ADI Scheme to solve Euler Equation of primitive variables, the 3D incompressible flowfield in turbomachinery is solved in present paper. After the pseudocompressibility is introduced in the Cotinuity Equation, the system of governing equations is changed from undefined type into hyperbolic type. Giving initial values and boundary conditions, the system of equations can be solved by use of Time-Marching Method to get a stable solution. 3D flowfield within the rotor of the single-stage axial compressor at the Pennsylvania State University is calculated in present paper. The prediction results quite agree with experimental data.
