摘要

对一级轴流和离心叶轮组成的组合压气机非定常流场进行模拟

通过影响因素分组法

讨论了上游轴流叶轮尾迹与下游离心叶轮势流共同对中间静叶气流非定常流动的干涉特性及离心叶轮势流单独对静叶气流非定常流动造成的影响

并得到轴流叶轮与静叶间、轴流叶轮与离心叶轮间和静叶与离心叶轮间的干涉现象对下游离心叶轮进口气流产生的影响.结果表明:当上游轴流叶轮叶片尾迹和下游离心叶轮势流在中间静叶流道内发生耦合叠加时

会导致两种影响因素出现彼此相互激励或抑制现象;在离心叶轮进口处

轴流叶轮与静叶间、轴流叶轮与离心叶轮间和静叶与离心叶轮间的叠加干涉相位不同

将会导致此处气流产生畸变

直接影响离心叶轮进口气流角的非定常波动幅值.

Abstract

Three-dimensional unsteady viscous numerical simulation was conducted on an axial-radial combined compressor to study the interaction characteristic of wake/potential and downstream potential effects on the mid stator vane.The axial rotor/stator vane

axial rotor/impeller and stator vane/impeller interaction effects on the impeller inlet angle were also investigated by using the effect factor split of the combined compressor unsteady flow.The results show that upstream wake and downstream potential lead to reinforce/suppress effect while coupling in the mid vane passage.Due to the different phases of axial rotor/stator vane

axial rotor/impeller and stator vane/impeller interaction

work fluid at impeller inlet encounters distortion

which directly affects the amplitude of inlet angle.
