摘要
通过求解二维可压缩N-S方程,对多级低速轴流压气机的一级进行数值模拟。用定常计算得到了该级在不同转速下的稳态特性曲线,进而得到其喘振线。在该级出口加上节流阀进行瞬态计算,模拟压气机进入旋转失速的过程,重点是失速先兆的发展和内部流场的分析。
The multistage low-speed axial compressor's first stage was numerically simulated by solving two-dimensional compressible N-S equations,and the steady characteristic curves of this stage were obtained through steady calculations of different rotational speeds together with the surge line;a throttle valve at the stage outlet can execute transient calculation and simulate the process while the compressor enters rotating stall,and can emphasize the development of stall inception and the comprehension of the internal flow field.
