Abstract

The flow in a four-stage axial compressor is investigated by numerical modeling using the Numeca FINE/Turbo software. A few approaches to modeling the rotor-stator interaction are considered: the steady statement with the use of the Mixing Plane boundary condition, the fully unsteady statement (URANS), and the non-linear harmonic (NLH) method. These approaches are compared by considering the time-averaged and instantaneous integral parameters of the compressor and the pulsations of local parameters.

轴流压缩机中的非稳态现象建模

摘要

使用Numeca FINE / Turbo软件通过数值建模研究了四级轴流式压缩机中的流量。考虑了几种建模转子-定子相互作用的方法：使用混合平面边界条件的稳态陈述，完全非稳态陈述（URANS）和非线性谐波（NLH）方法。通过考虑压缩机的时间平均和瞬时积分参数以及局部参数的脉动来比较这些方法。
